Default Help!!!!!

Hey Everyone, ran into a problem tonight while throwing my motor together. Ill start from the top. its a gen 3 5.3 that was bored 30 over, factory style forged 30 over pistons, scat rods, and ls1 crankshaft. the problem is that I am having ptv clearance issues. so here are the cam specs

bullet racing cam
.226/.234 @.50 .590/.590 115+4. 7.400 push rod, .650 pac springs, stock rockers, cloyes timing set put on at 0 degrees.

I'm pretty new to the ls stuff so I am wondering why I am having the ptv issues, plan on calling bullet tomorrow just thought I would see if anyone here could shed some light on it.

Flat tops pistons with valve reliefs?

What measurements are you coming up with? How are you measuring?

You've left out a good bit of information for anyone to help.
