.020 over?
.020 over? Pulled a spare lt1 that has been rebuilt before and has speed pro cast pistons from what im told they have 245np on the piston i believe. If i remember reading right they are lower compression than stock. So is there any forged. 020 over pistons that arent exspensive as hell just plan on a cam and 150 shot for now.
.020 over pistons? 
Kinda an oddball choice...the vast majority are .030 over or more.
Speed pro does not make any .020 cast piston...the only one they have is .030 over which is the standard overbore size. Are you absolutely sure they are .020 over?

They do make a .020 over Hypereutectic piston however:

Thanks for the link xjs and mystery bird I was actually looking through your build trying to figure out whhat pistons you used, I like the je's but they're a little exspensive for my budget so I think ima get some speed pros and scat I beams.
Try findimg a good ring for a .20 piston. Its not easy. I bought a block from a guy that had. 20 pistons wanted to re ring it and found its not common at all. Go. 30 and be done with it
