It was a 330 cylinder bored to a 78mm so the dome was the wrong size for the piston. He got a new dome from esr and got it running now.

i am assuming that you bored the cylinder to the next size up the dome has to be cut for the next size up piston because the piston is supposed to go up inside the dome on stroker

the motor was bought without the head on it and when he went to assemble it the piston was hitting the head. the seller didnt to tell him it was a 330 bored to a 370 just said it was one.
