I'm to a point now when it's time to order some custom pushrods.

BUT...there is one final aspect I need to resolve and would like the group's recommendation.

The combo is a 408 stroker, race econo W2 heads, Harland Sharp 1.6 ratio rocker arms. So these are the roller rockers (nose and the shaft) and per their specs they recommend restricting the oil feed to the shafts. Cam and lifter is a hydraulic roller setup, Comp Cams.

I have not restricted the oil yet, however I made a provision in the heads theselves to do so by threading the oil feed passage so that an adjustable orifice plug can be installed afterwards w/o having to pull the heads and rely on the block version of this adjustment.

Alright, all good so far.

Now I need to decide whether I should order the oil through pushrods. My thinking is that if I do in fact restrict the oil feed to the rockers (no plans to start off with, but if I find that I need to do so I still need to bring some oil up to the rocker arm - pushrod interface where the rocker arm adjuster meets the pushrod cup).

On the surface this wouldn't seem to hurt anything, heck, more oil at the highly stressed (friction) areas is a good thing. But is there anything else that I'm overlooking here?

I do realize this is basically a controlled "oil leak" situation, but this being a street engine with majority use being wide RPM range, I do not think that is an issue (I am using a bigger oil pan with a high volume pump).

Yey or nay?

Thanks everyone!

I recently did a 408 with a hyd. flat tappet stick , Comp steel rockers and oil through push rods.
I didn't restrict anything , but spent a good bit of time prepping the block for drain back , opening up the feeds to the mains to enhance rod oiling , etc.
High volume pump , scraper , big pick up etc.
It didn't appear to be drowning the top end while I primed it
. It was built for a street / cruiser / toy , and it has great pressure across the board.
492 and 492 on the pump , it should behave well enough to run A.C. and still enjoy the ride.

I would install a .040 to .080 restrictor for those rockers if you have full time oiling to the shafts, if not full time oiling don't restrict them

I did not enlarge any of the passages, but I did clean up the regular block casting openings, removed a pile of the rugged flash just sitting there. Cosmetic mostly I think, but easy to do once and at least it gives me a peace of mind.

Appreciate the feedback, thank you!

OK, good suggestion. Right now the setup is configured for full time oiling, so I will take that into consideration as it gives me a starting point.

If I was to use the restrictor though, at which point in time does it become preferrable to use the oil through pushrod setup as well?

All my previous builds have used a non-oil through pushrod, but as tubtar pointed out: that option has worked for him fine so far and getting direct oil feed to that pressure point seems like an opportunity to rule out a potential problem from developing, so why not? (at least that's my thinking at the moment, and after all this is a NEW parts spend for me, so I might as well purchase the best solution)

Thanks as well!

So, not the factory interrupted “through the cam” oiling?

Oh...nope, this is still the factory setup. I never got the cam journals groved to provide non-stop (thus the meaning of "fulltime" I suppose) oil feed.
