Ok here's what in wondering. (Because I don't have the extra money to bore to 5.7) I have a 04 lm7 decked and hot tanked and honed. I want to run 05 L33 flat tops and rods. My heads are 706s that are being done up now with bigger valves and pp. Can I run those pistons and rods and not have any problems? Will the ptv be ok if I mill the heads another .010 to tru them up? Will i gain more compression if I do? Sorry for all the newbie questions but I just gotta no so I can start ordering parts this weekend. And I'm on a half a$$ budget but would u buy forger rods and slap some stock pistons on them or not !? I'm try'n to build something thathat has some pretty good power
