b20 or b16(p30) pistons?????
i have a ls block and was wondering if i should use b20 high compression pistons at a 85mm bore or p30 pistons at a 81mm (std)..i am using a b16 head,,this is for a ls vtec build...with which piston will it run better and will i require higher octane gas?

umm what?
either 85mm or 81mm?
more air=more power
just buy a b20 block for 200 bucks and put some pistons in for 150 and be done with it
