What is wrong with my motor? Figure this one out!!

[Mr. Chevy]

The motor is coming back out tomm. and will be sent back to the builder all together. He said he wants to carefully take it apart and see what is going on... Hopefully if the piston/head clearance is the problem the heads can be slighlty modified to where it will work and I won't have to replace the pistons..

Maybe it's a combination of both lifter/oiling problems and piston to head clearance.. That would be my luck of course!! I tell ya if I didn't have bad luck I would have none at all!!!
