Piston hitting spark plug?
My engine is at a machine shop to break in the cam and I just got a call saying it's locked up and the Pistons were hitting the spark plug. Engine is a 2 rms 355 with vortec heads and I used auto lite 605s. I've done some more reading and the 605 seems to be a popular choice for these heads. Does this sound right?

Autolite 605's are good for those heads.
Do you have dome pistons?
