no oil to rh rockers

Barracuda_v8 said

I just started up my engine tonight it sounded great but i didn´t get any oil to the RH rockers. took the bolts out were the oil should come on both sides and ran the engine on the starter. on the LH hole there came lots of oil. but absolutly nothing on the RH side. HELP!!!

I've noticed that ARP head studs restrict oil flow when used on Edelbrock heads. A typical head bolt has a thinner shank (as compared to a stud that doesnt tapper) allowing oil to flow around the head bolt, thru Edelbrocks oil galleys.

What heads, head fasteners and head gaskets are you using?
