Trunnion kit. we swap em on all ls

I would stay with the stock rockers in your case. We've seen failures with those too.

So a brand new unfired GMPP crate engine had bad rocker arms right out of the box? That doesn't sound very encouraging..

The engine had 25-50 miles on it long story the engine was in a car that had a small fire. 1960 Chevy it was in caught fire but they got to it within a min or two so just the intake and other plastic parts were melted. The engine did have water in it for some time. Thinking now two lifters may be bad.

I'll order the Trunion kit anyway just to cross that out

could lifters feel spongy? Think they just need to build up pressure maybe from cranking the engine over and not starting all this time could of drained the oil?

Should I replace them dont really want to pull the heads

:confused59:

The fire would have been helpful info to pass on when looking for help diagnosing the start up issue:headspin:

You should make sure you have good oil pressure before starting. LS motors can be difficult to prime. Remove the plugs, disable the ignition and fuel and crank til you have good oil pressure. This is quite important.
