Stainless, Bushed PRW Rocker Arms

JDMopar said
Are you using stock head bolts with the TF heads, or did you use studs? If you used studs, oil may not be getting up thru the passage under the longest head bolt on each side like it will if you use factory style head bolts. The longest head bolt on each side is smaller diameter to let the oil coming from the cam passage up to the head get to the rocker shaft. Head studs are full size and will cut off or severely restrict that oil flow. Also, check the shim for the correction kit to see if oil will get past it and up into the rocker shaft like it's supposed to. Just throwing another idea out there that will be easy to check. Hope you get it figured out soon.

Interesting,
I used studs I got from Trick Flow.
Thanks for that.
I did however run factory 273 Rockers
With Banana grooves on them for several thousand miles with no wear.
They are back on currently and seem to be working fine.
One member suggested taking them off
One side at a time and remove all spark plugs, cover the oil hole with a cup then crank the Engine to watch how much oil is getting there.
I think that would help answer that question.
Actually If the 273 Rockers keep living I might just leave them on.
I don't think the Geometry is as good.
As long as it doesn't cause any excessive guide wear or valve tip wear...
Thanks
