Installed HS rockers on my EZ 295's with external oil kit. Cold oil pressure was at 70 psi and hot oil pressure was 52 psi all at idle.

On the track, oil pressure was at or about 65 psi at 6800 RPM.

Returned to the pits and installed Indy oil restrictor kit. Oil Pressure hot at idle was 70 psi. These restrictors have a .040 orofice.

High RPM on track, oil pressure was at 78 psi.

My question is, has anyone run this set up with the indy restrictors? If so, have you had any problems with oil volume to the Rockers?

I pulled one valve cover while at the track several times between rounds on the way to the final and I did not notice any issues. Pushrod cups looked good and still plenty of oil on the rockers themselves. Just a new set up with nine passes on them now!

You'll be more than fine.

Im not familiar with the Indy kit, but a few years back I made my own restictor. I used the Y fitting in the back of the block and drilled and tapped it for a holley jet thread. Now keep in mind I used a #70 jet which is .070" this was feeding both heads through this one restrictor. This setup T'd off with oiling line too each valve cover. I made my own using 3/16 brake line, various inverted flare fittings and NPT fittings..
It worked great. It really doesnt take a bunch of oil in a drag racer application to keep everything happy.
I never had a single problem. This was with a Jesel setup. I have seen people who has problems with burnt pushrods and scored valve tips etc.
I dont know, this block I ran had very little oiling mods done if any at all. I ran the internal 3/8 pickup and a 4x4 truck pan running my home made oiling kit for the valve train.... Go figure?

Thank you for your comments. The .070 jet fed two 3/16 line (correct?) That would also lead to concern for me because my two .040 restrictors are feeding the shaft inside diameter. Which i am not exactly sure of the measurement. I guess as long as the shaft is able to fill and build pressure without oozing out too fast i will be okay. Hoping to find someone that has ran this exact set up that would be able to give their two cents.

Both of my oil lines to the heads are tied into the 'T'. My oil pressure comes from the other outlet on the block.

I have read McCandles' (sp?) article on blocking off the feed to the driver side lifter valley. Maybe I should have restricted my oil there with the plug and a small orofice and kept the volume to the rockers!

I have about 270 seat pressure. Unknown open but should be somewhere between 550 and 600. Just fixed a pushrod oiling problem and would hate to scatter needle bearings throughout the motor.

I really didn't have any worries until i saw the tiny orifice in the restrictors i put in! Man they are small.

I tell ya what I am going to do. I am about ready to fire this new Hemi and I have the valve covers off now double checking everything. I plan to prime the engine up with the covers off and make sure oil is getting to everything, and has plenty of flow.
This is the only way you will know for sure IMO.
This Hemi stuff is new too me, but this way I know for sure that all the rocker shafts are oiling as they should before I fire it up.
I dont see why this couldnt be done for a wedge like yours either.
Now my cam has the journal grooved so Im not sure how it will oil, But I plan to bump the engine over slowly after a few seconds to see if there is any changes. This would be must with a wedge, unless the journals are grooved. I always felt even though someone said it would be ok, I still checked things out my self, cause frankly the money to fix any avoidable issues is just a waste, not to mention expensive.

With the oil pressure you had, the only reason I could see for running the restrictors is to reduce flow to the top end, not to increase pressure. Your pressure was fine.

your oil pressure and volume at the rockers will depend on the oil pump volume size.

i also just put h.s. rockers on and have the restrictors as you do. i have .049 orfices and it still pumps the pan dry, have to run it a quart over full of oil. i am going to change mine to .038 or so. but i also have big oil pump.

Just as a side note, of you have seat pressure of 275, you'll have may more than 550# of open pressure. Good luck with it all.

Now were talking! Great info.

As far as oil pressure goes, shouldn't I have at least 10 psi per 1000 rpm? Since my rpm was exceeding the oil pressure by ratio, seems that i would be risking bearing damage, no?

I did prime the motor with the original indy oil fittings and yes, tons of oil. I just have not had a chance to prime it since i got back. I will do that though.

My original fittings seem to measure .120 orifice. Indy reports that the restrictors are .040. When i inquired about .060 I was told that I would be right back at the original fitting size! Go figure. I was hoping to find a few variables with their insert restrictors. I guess drilling and tapping the heads for Holley jets is the way to go.

Forgot to add, Melling HV, 1/2 internal pickup, 7 quart pan. No other oiling modifications.

Again, thank you for the info. I'll follow up with more info once i pull the covers and prime the motor again.

The best and surest way is to still just pull the adapter fitting out of the heads, and yes, drill and tap for the Holley jets. Works extremely well. You can also simply use sets screws and drill the hole of your choice. Done both, both are foolproof.
