Potential, cost, porting options, etc.
PS..
I have already read the info from the RHS site about these, just want more real world info, porting cost/benefits, valve size upgrade needed, how big of lift cam can be used, etc, etc.....
69 Dart GTS A4 Silver All steel, flat factory hood, 3360race weight
418 BPE factory replacement headed stroker, 565 lift solid cam
Best so far, 10.40 @127 1/4
1.41 best 60 foot
6.60 at 103.90 1/8

Yep, what they said...call Brian. Depending on your goals, these are GREAT heads. If you're looking for 750 HP? No. But they can support in excess of 600 easy. The best part is the cost...
My REAL WORLD experience was a pair bought from NOT Brian in the LA versions with a 2.02 intake, Comp 26995 Beehive springs, ret, locks ready to run. We took them apart and chucked on a known bench to see the flow #'s. The number's really don't matter as your actual mileage (and flow #'s) will vary. But I will tell you that with a GOOD VJ added, a little (very little) blending of the guide boss and unshrouding of the chamber, they improved about 10 cfm to 268 @ .600", the same at .650" and going backwards above that. We called it a success and plopped them on a motor for the Duster and here are the specifics:
*416
*12.2:1 Flat top (KB Forged)
*SCAT I beams
*Eagle forged crank
*The aforementioned RHS heads
*Comp Stainless 1.5 rockers
*Custom Bullet solid (non-roller) cam (268/276 @ .050 w/.585 net lift)
*Old Victor intake (with a minimal plenium blend)
*REALLY Old 800 Holley (tuned it to 848 on our bench)
*2" open spacer (because that's what fits the air cleaner/carb/scoop/seal deal)
*Hooker 1 3/4 headers
*Dynomax 3" Bullet muffs
904 (standard low gear)
8" Converter (5200 real flash in good air)
4.56
29.5 tall slick
dead on 3100# race weight.
Cal Mono Springs/Cal tracs...
Best so far: 10.14 @ 128 (107 in the 1/8) with a 1.42 60' best. If I can just get that 60' to a solid 1.35...

I can't tell you much other than that these heads flat out work, and Brian is the man to get them from With these heads and a custom ground comp hydraulic roller on my stock junkyard bottom end 91 360 LA motor my 4 speed 3400lb street car runs 12.3-12.4 all day long on 87 pump puke! This motor is nothing fancy at all, in fact the heads and cam are what make it work so well...so I can just imagine the potential it would have on a bigger motor...which reminds me, if you want a cam to work with them, Brian will spec you out an awesome one!  good luck!

cudadoug, what's your shift point rpm's
very impressive combo
Sorry didn't see this until now:
6,400
2nd time at the track, we were at 5,800 and it went 10.42 and .41. Raised it 6,400 (only chip we had for the shift light) and it went .33 and .31 with no other changes.

great info, sure appreciate it. Sure sounds like a cheap way to do what i want, mid-high 11's on pump gas without a stroked motor. Just wonder in say a 3400 pound car, how a 360 with about 10 to 1 compression, maybe a 9.5 inch convertor and a set of those heads would run with a mildish cam if the combo was scienced out correctly.

this is what im thinking for myself as well...my bottom end took a caput, so once I open it up i will know for sure the damage...but i was thinking of a good forged piston get 10.5:1 cr, good quench, and a little more cam, might just put me at a high 11 with these heads in my 3400lb 4 speed car
a stroker is in the cards too, but as of now im not 100% sure i can swing it due to funds

I bought mine from hughes ready to bolt on in stock form, now the price at the time was 800.00, I ran 12.5s at 105 with a race weight of 3200+ lbs., this was with a junkyard 360 magnum shifting at 5100, just bolt-ons, 3.73 gears & an 11" 2800 stall, 650dp. These heads are still great in stock form, just depends on what your after.

Don, I think your goal is very do-able! I'd source a 5.9 mag to run a custom ground hyd roller with OEM lifters, 2.02 RHS heads, air gap, 750 carb, 1 5/8 headers, 904, 9" or 10" converter...and there you go. Might take a 3.91-4.10 gear to get there. But it makes me ask: Why not a 4.00" crank combo?? Here is the logic behind my question:
Crank: Cast 4.00" crank can be had for what...$250-$300? What's it going to cost to mag, turn and polish an OEM crank?
Rods: SCAT I-beams (no block grinding) are $300. What's it cost to have OEM rods redone? Here in CA it's about $250-$275 done RIGHT with ARP hardware
Pistons: Yea, okay you can get $300 Hyper KB's but the Forged KB for the 4.00" crank are in the $470-$480 range.
My points are:
1) Nearly the same $$ to get a cast 4" crank vs. a OEM redo
2) Rods...ditto
3) Pistons are on a couple of hun more...
5) Balancing? You'd have to have the 360 balanced also, right??
For the additional 50+ ft lbs of torque, the few hun it takes to build a "street" 408 is a pretty good deal, IYAM (New one: If You Ask Me...LOL) You could be in the mid-high 11's with a 3.55 gear!

yea I got to thinking about the cast crank idea myself. In the last article Brian at IMM did for car craft I believe that motor pushed 622hp on a scat 9000 series cast crank. I have read nothing but good about those cranks...just not sure how strong they are compared to an OEM 360 crank? some say they are great, others say they wouldnt trust them
whats a guy to do 
Either way though, the RHS heads would be a great foundation for either build

Don,
Brian recently built a 360, stock crank/rods/KB107's, 2.02 RHS, Comp XE275HL hyd cam, Air Gap, 750 DP, headers.
Made right at 430hp and 440tq
Not a crazy build and capable of 11.60-11.80's in a well set up car, that I know you are more than capable of putting together.
There are a bunch of different flavors of these heads floating around out there. Make sure you pay attention to the parts that they come with, there is a big difference.

All good points for sure
I have already had an 11 sec cast crank 416, a 10 sec cast crank 416, and a 9 sec forged crank 422 motor.
I know me  ...and i were to do a 4 inch shortblock, it would be stout and have a good block wrapped around it...it would only be a matter of time before i have what i used to have, a 95% track, 5 % street car that i would sink a ton of money into....because at that point i would WANT to go 10.0 racing again. I have a harley to buy this winter, so the car has to kinda eat off the same plate.
For me, a little 340/360 will do all i want this car to do at this point in time, it will have " limited upward mobility"  , and i wont have to worry about wheelstands with a shorter arm 
I also dont want to put a roll bar in this Demon, so 11.50 in mineshaft air is all the better it would have to run to make me elated. Think i can do that with a production block, these rhs heads, and not even have to really lean on it to get there, and it should live to fight a lot of days.

Thanks, good advice.
Actually am kinda leaning toward a 360, it will make a little more torque than a 340, and me being as big as i am and the car being full weight, it might ultimately 60 foot better with a 360 than a 340, and i kind find a block easier. Guessing it will need to make about 460 or 470 with a 904 to get me where i want to get.
Probably like a tti header, weiand excellerator( i love that intake.. and the 318 that was in the demon when i bought it has one already sitting on the motor), proform 750, maybe a hughes flat tappet somewhere about 246/252 ish at 50, that will have a decent little thump, a ptc 9.5 convertor, 4.10 gear and leafs and 8 inch wheels and 10 inch tires.

That's a bunch more cam than you need... 
I think the 275hl intake is 231 at .050. I'd bet that cam you state would get you a bunch closer to the 460-475hp mark.
Hard to beat the RHS on a bang for the buck basis.

Hahahaha! Eat off the same plate! I love that!! Me, too...except it's the rest of my overhead that has to eat off the same plate...and there are only so many forks, lemme tell ya.
Actually I know where right where you are. 11.50's are my threashold on my Street car project, as no "pipe" is in the budget! I'm just going to do the 408, as I already have the SCAT crank. And I want to go high 11's with a 3.55 gear!  But I agree 120% on your thinking with the 360. Done right it will get you there and a MUCH easier (= cheaper) block to find than a 340.

Probably like a tti header, weiand excellerator( i love that intake.. and the 318 that was in the demon when i bought it has one already sitting on the motor), proform 750, maybe a hughes flat tappet somewhere about 246/252 ish at 50, that will have a decent little thump, a ptc 9.5 convertor, 4.10 gear and leafs and 8 inch wheels and 10 inch tires.
That's a bunch more cam than you need...
I think the 275hl intake is 231 at .050. I'd bet that cam you state would get you a bunch closer to the 460-475hp mark.
Hard to beat the RHS on a bang for the buck basis.
kinda the reason i was thinking a cam in the mid 240's at 50 is because i want a little thump, and something like that on a 108 will sound pretty cool. Also my little brother has a 360 in his 66 Dart with Eddies on it. Its about 9.5-10.1 compression and runs pretty decently, he has been 11.38 with it at about 117 at 3300 pounds( bone stock interior and no fiberglass with a 904) he has too big of a cam in his car( 258-264) yet it still runs respectable with his 8 inch convertor, so i figure something 10 degrees smaller and otherwise similar combo's should be a nice compromise. He has a 750 and an excellerator on his( that i gave him) and dinky headers.
I see Hughes makes a 246/252 thats ground on a 106, with about the correct lift with a 1.6 rocker. With that tight of LSA it should sound choppy.
69 Dart GTS A4 Silver All steel, flat factory hood, 3360race weight
418 BPE factory replacement headed stroker, 565 lift solid cam
Best so far, 10.40 @127 1/4
1.41 best 60 foot

Don,
Brian recently built a 360, stock crank/rods/KB107's, 2.02 RHS, Comp XE275HL hyd cam, Air Gap, 750 DP, headers.
Made right at 430hp and 440tq
Not a crazy build and capable of 11.60-11.80's in a well set up car, that I know you are more than capable of putting together.
There are a bunch of different flavors of these heads floating around out there. Make sure you pay attention to the parts that they come with, there is a big difference.
Thanks, good advice.

I think you're on the right track, Don! I am looking at about the same cam 258-ish/265-ish for the 408 after talking to Bullet. Tim and I discussed a 360 combo as well and he had the same thought; trim about 10 degrees off for the 40 cubic inch diff.
Now I have questions about his ride: Are the Eddy's "stock"? What gear/tire? Street driven?? What is the converter flash/stall? It sounds like it runs REAL good at that weight.
