I’m looking at moving to a new set of rockers to add some ratio / lift to make better use of my heads. My current rockers are bronze bushed units, I’m looking at a set of needle-bearing roller rockers. My assumption is that this change at the shaft would release a ton of oil pressure. (Correct??). Do I need to install a restricter somewhere? Walk me through this please.

Engine currently idles around 45psi and runs at 70psi, 80 at higher RPMs.

Thanks-

If you have Indy heads you can restrict the oil at the rear oil line feeds they have, if not Im not sure.
I am not a fan of needle roller rockers as I have had one fail putting needle bearings through my engine, one found its way to the oil pump which stopped the pump, snapped the drive and the engine kept running frown

CNC’d Stealth heads. Stock oiling.

Assuming a stock oiling system, you should have no problems. That being said....
If someone has altered the #4 cam journal or bearing with a groove, (common practice that I am strongly against) you best have some sort of restrictor in the supply drilling from the cam to the deck surface. With a grooved #4 cam journal, and no restrictors, you WILL lose about 60% of the oil to #4 main, and #6&#7 rods.
Even if you didn’t intentionally alter the oiling, some cam companies alter the journal to save valve train parts (at the cost of the bottom end)
There are better ways to get oil up top.
Hopefully you have a stock oiling sytem. The stock oiling sends oil in pulses up top.

I tapped the rocker shaft oiling hole on both heads and screwed a brass set screw in with a .060 hole in it. That way if I wanted more or less oil I could simply remove the rocker shaft and go bigger or smaller. I bought a bag a brass set screws off ebay.

Im not up with small block but the oil comes up the sides of shaft hold bolt on big block.

SB are the same except they don't oil both sides through the #4 cam journal scope

If you’ve done no modifications to the oil system that result in having full time top end oiling, then just bolt the rockers on and go.

hmmm... my 451's cam came with the #4 journal grooved from the factory. It's quite small in width and depth as I remember.

Is there a simple way to add an oiling restrictor with the engine together? I don't want to have to pull the heads to drill and tap. Thanks.

I would leave the rockers alone and put in the correct cam, lifters and timing set. Fast68Plymouth spec'd an amazing cam for my build. Not knowing what you have now, increasing the ratio on your rocker arms may do little or nothing to take advantage of your set-up. It's all about the combination.

There is one way. If you look into the feeding pedestal typically you'll find that the top of the bolt hole is counter bored then the bolt thread starts. In the area of the counter-bore you will typically find the oil galley feed point. If you use thin wall tubing you can sleeve the counter bore area with a pre-drilled bushing made from the tubing.

& you could stuff a piece of rag down below the angled feed hole to manage the debris then drill/tap for a setscrew drilled to what you want. that gives you the option to go larger/smaller in the future as (if) needed. Ahead of time I do this to all (5) vertical cam feeds from the mains down to the cam journals & drill each setscrew to 1/16" which is plenty for cam bearing/journal lubrication (1/8 on ones that feed the heads if going that route but on those (2) I do them all to 1/16 & feed the heads externally or from angled valley oil passage mods) so I can do all (5) to 1/16".

If you have stock oiling I would do like Dwayne said and bolt them on. Mine is stock oiling with high volume pump and 1/2" pickup but all stock oiling other then that. I use roller tip Hughes rockers that are not needle bearings at the shaft and mine has been flawless with no problems at all in 7 years so far. I think with stock oiling you should be fine. Is it a good brand rocker as I have heard some bad stories on some of the cheaper shaft needle bearing rockers ? Good luck what ever you decide. Ron
