Doesn't sound like a lifter problem.
Did you measure for pushrod length after changing the cam? Whats your lifter preload?[/quote] I have tried pre-load at 10thou and now have preload set at 45thou and still same prob.

if its just a ticking noise, its probably fine, if its a tapping or knocking noise theres a problem, I've found the std bolt on yella terra rockers to be noisy, regardless of how they are installed.

Yeah, it sounds like it could be the bolt on yella terra r.r.s . It was a bit rattly with standard cam and 1.72 r.r.s and is worse with 2031 cam and head work done also flash tuned and running a healthy 220rwkws.
After trialing diff preload settings, valve train geometry blah blah blah Not sure weather to try a set of adjustable r.r.s (different brand) or roller lifters.

Fairy all i ment by the bolt is that they are the standard non adjustable bolton roller rokers nothing to do with any bolts, just the old bolt on pedistal roller rockers.

Ive changed gaskets for paceys and made sure no leaks this is not the cause of my prob, but i agree on your thoughts,check and double check exhaust manifold leaks before opening up engine
