Piston pin bad ?
Not sure what happened to the rockers since I was hyper vigilant about assembly , oil priming and checking supply of oil to rockers. Yes I installed the shafts properly...also rotated engine while priming ( I primed the heck out of it.) so much that I started to worry about the oil washing the breakin lube off cam.
The thing is that I had to return the first pair of shafts to Hughes because they ballooned when I installed the oil plugs in the ends and I could not get the rockers off the ends of the shaft.
