Please help new to all this new Hemi stuff Im Old school type used to my old BB's

Any way I bought a Jeep Commander that dropped a Valve seat, I got it out today and got it all torn down to get it off to my machinist to bore the block.
The LH Head is trashed #7 Intake seat took the plunge and fell taking out the cylinder head and the Piston the Block will clean up.

So now with the questions

The MDS solenoids where destroyed removing them no big deal as I want to get the Kit that eliminates it.
I plan to buy a Cam and lifters after what I just read about the lifters failing in between 30k-120k. mine have 194K I think they are done lol. Suggestions?????

The heads I have and will be running are a set of Eagles already rebuilt and I have my eye on a set of long tube headers any cam suggestions for a Truck? planning Hiway and 4x4 ing mostly.
Arguing with my son as which head gaskets to buy as well I say at least a .075" thick he wants me to stick with a .030" I know these heads will increase my compression but I dont know how much?

I am also looking for a Good Rod and Piston combo. Forged pistons with Good I beams or H beams any suggestions without breaking the bank Strong is what I want????

This is gonna be a Hotrod truck NOT a race car and will never see a track and never be raced just Hiway Dirt roads some hill climbing crawling threw rocks 4x4ing maybe some Mud once in a while..
I want longevity and reliability with a Boost in power is what I am looking for oh and I don't have to worry about passing smog!. 400hp on pump gas???? is that doable? is there more there naturally aspirated with these heads?

I just want it to live a LOOONG time and make respectable power.

Others with more knowledge can chime in but I have heard of a lot of people running hellcat lifters which you can order for relatively cheap from the dealer and they are non-mds lifters. I have read a lot of people have had good luck on parts through http://www.modernmusclextreme.com/

Get a piece of plexiglass, drill a couple holes in it, get some grease and a 100ML syringe (1ML is the same as 1CC) ,
measure your volume and calculate your compression ratio.

Comp 268, eagle heads with .075 gaskets, custom pushrods and long tubes is a known pretty happy combo.

If you want "the sound" but need it to be tractable, that's the easy route (or something really close).

If you DON'T want "the sound" and need it to behave really close to stock, then get a Comp 260.

Thanks But I am not gonna CC the combustion chambers there a well known off the shelf head with known cc's
I will find out what they are.

Has any one tried Crowers EDM roller lifters? supposed to have a tiny hole drilled into bottom of lifter too lube the roller?

If they had MDS I would be all over a set today! $300 cheaper than stock and they at least tried to do something about the roller failures.

Am I missing something? Shouldn't a 2010 already have Eagle heads? I have a 2006 Commander Limited 4x4. My Hemi is spewing oil. I think it is the rear main (160K miles). Not sure what I will end up doing, but I am kind of in the same boat looking to upgrade, but it is mostly my wife's truck. My goals are similar. In 2009 they got a bump from the 330 hp my truck has to 360 hp. I think that was mainly the Eagle heads. I don't think the later Jeeps have VCT, but otherwise it should pretty much be the same as most later 5.7s. If that is true, you can count on killing compression with the bigger gaskets.

I think 400hp is a pretty modest goal. 40 hp from worked heads, long tubes and a cam? I would be disappointed if you didn't get that much. I think some of the later 5.7's are at 395 stock. I have seen mild cam upgrades claiming over 400 and increased power throughout the rev range." 400 should be realistic and obtainable.

I'd be interested in what parts you and others suggest for the this type of combo and how hands off the long tubes are after install.

The Eagle head is a closed chamber design, even with a Compressed head gasket of .075 compression is gonna be over 11:1.

I am thinking about the Crower cam 33494 213/222 @.050 528/548 lifts 114 center. with the 66323PH-16 lifters.

Adding the MDS deleat plugs and new MDS deleat yokes as well. cometict head gaskets and ARP head bolts IF I can ever find them???? I dont want studs Summit web sight SUCKS!!!!
Decided to just recon my old rods with new bolts ARP again if I can find them? Maybe a new set of Stockers again if I can find them at a decent price Im only after a 450 hp build no reason stock wont work.

Still looking for pistons.

I just found a Re-man long block for $4300 from Chrysler hmmmm I have to do more research and add all this up!

This is not a BB of old with detonation issues at 9 to 1. They tolerate compression waaaay better. I have just over 11.5 in my very heavy 2011 4 door 4x4 1/2 ton 6.4 SRT hemi short block 3.55 gears and like I have said, no pinging on the knock sensors on premium pump gas. Also the early 5.7 is not going to be as high as everyone says when you actually measure it yourself, I have done it and it is barely around 11 to 1 with a stock head gasket. Measure everything yourself and tell us what you actually get, don't just go off internet numbers, often they are going off what they heard from someone else or what the manufacturer threw out that may or may not be (most likely not) close to reality.

Dave I get what you are saying
BUT this is a Hot rod build NOTHING more! I could care less personally I just wanna be close, If the MFG says X CC then thats it thats what I am going by.

If I was racing it Ya sure go all out but I have nothing to prove to any one this is just a Hot rod to go Rock crawling playing in the desert im sure a .075 head gaskets will get me close to 11:1

I would go 6.1 SRT non mds or hellcat lifters. Stay oem and avoid the seedy aftermarket replacement offerings. On the cam, I would go with a 212/212 on a 115 in a 5.7. It will idle with a stock tune, but you'll need a programmer to eliminate mds.

The heads I have and will be running are a set of Eagles already rebuilt and I have my eye on a set of long tube headers any cam suggestions for a Truck? planning Hiway and 4x4 ing mostly.
Arguing with my son as which head gaskets to buy as well I say at least a .075" thick he wants me to stick with a .030" I know these heads will increase my compression but I dont know how much?

You will be at 13:1 with this set up. I would run early 03-08 heads cut .030 instead of the eagles for this one. You'll have an intake mis match if you run eagles on a stock style intake and you'll have to run adapters.

I am also looking for a Good Rod and Piston combo. Forged pistons with Good I beams or H beams any suggestions without breaking the bank Strong is what I want????

You don't need rods and pistons at this level. Up to about 550 you're fine. If you really wanted you could get a set of Modern muscle drop in rods and pistons but its completely not needed.

This is gonna be a Hotrod truck NOT a race car and will never see a track and never be raced just Hiway Dirt roads some hill climbing crawling threw rocks 4x4ing maybe some Mud once in a while..
I want longevity and reliability with a Boost in power is what I am looking for oh and I don't have to worry about passing smog!. 400hp on pump gas???? is that doable? is there more there naturally aspirated with these heads?


The stock motor with just a cam will make 375rwhp. So you've already beat your number at the crank. If anything, the hyper pistons will work better long term for you and not eat the bore up like a 2618 forging would. You've got a 300cfm head out of the box. You don't need head porting for this.
I just want it to live a LOOONG time and make respectable power.



You would be better off running those eagles on a stock 6.1 block or a built motor with custom pistons.

I've got 5.7 ported eagles on a 6.1 block with 6.1 head gaskets for 11.25:1 and a 219/231 cam. Should be over 500 hp with my stock 6.1 intake.

Simple will work best for you. This isn't the right combo for eagles. A cam only 5.7 with stock heads will do what you want.

I repeat my prior question:
DOESN'T HIS CAR HAVE EAGLE HEADS TO START WITH?

It is a 2010. My understanding is that the 5.7 got Eagle heads starting in 2009. They are not some exotic thing, they were an upgrade. He doesn't have an early Gen3. Eagles should be the stock head from 2009 up. I don't see how this isn't the right combo when they are the factory head. I also don't understand the agita about compression ratio. If I am wrong, please educate me.

If i read his title right it is an 07 Jeep Commander and he has Eagle heads from 2010 for it.

So if its an 07 then stock it did not have these heads.

There you go. I didn't read it right, even though I read it more than once! Sorry. That makes sense. I thought the Eagles were much less prone to dropping valve seats in the first place.

TLDR I am an idiot!

The title says 07 Hemi Commander, which would be a 03-08 motor, Then it says 2010 5.7 eagle heads.

So what I gathered is that he has an early truck and wants to upgrade heads.

For all real purposes, the eagle 5.7 head should be treated the same as a 6.1 head, but with closed chambers. The intake port is much bigger than an early 03-08 5.7 and the exhaust is a d shaped port that works with a 6.1 header best.

The loss of quench is more critical to me than the gain of compression for this mild application. The 09 5.7 Hemi was at like 375 hp anyway. Add a cam to the early motor, be done.

All of these heads drop seats, some more than others. I've seen eagles and 6.1 do the same thing. Its luck of the draw.

Thanks for the replies Guy's

You guys are correct its an 07 block & crank, And yes 2010 Factory Eagles Heads.
Alex is correct the later heads do and will drop seats just like the early heads.

The Block has to be Bored to save it #7 Intake seat dropped and it broke the piston scaring the Cylinder.

I found and am Looking at Factory new Rods and Pistons from Ma'Mopar 5.7 and 6.1 are available BUT they are only available in Stock sizes though.
Stock bore wont work as my block needs to be bored, So I am looking at the Stock 6.1

Rod and pistons from Ma Mopar includes new rod, wrist pin, rings and rod bearings for the 6.1 are $122 each. Its a Full floating rod and flat Top piston.
Not a Bad deal when you start adding everything up.

My understanding is that the rod length, compression height and Rod Journal are shared from the 5.7 and 6.1 is this correct????
The 6.1 just has a Much larger Bore.?
If I can Get the 5.7 block to accept the Big bore it would save me a Little money with some nice factory parts.

The only time I have seen dropped valve seats in these is when they overheat, either the customer has admitted this or usually you can see discolored metal and sludge through out the engine indicating this is what happened. I have seen a lot butt every time it is overheating.

There is a guy (in seattle I think) that sells bored out 5.7 blocks and calls them 6.1s and I have heard of others doing it and using STD 6.1 pistons.
