looking to get a b20b or z for my civic and just want a little edge..

have been looking at piston options but looks like everyone who makes high compression pistons only rate it for vtec heads and sometimes an ls head.

what is the reason and any suggestions on pistons with still keeping it on pump gas because this is my daily?

and what are differences in heads between b20b and z? or would i benefit more from an ls head?

thanks for all the help

 

Correct me if I'm wrong but I believe the B20 head uses the same components as the LS head. So as far as pistons I would think that any LS pistons in the proper diameter will work.

 

b20 head is the same casting as ls head.. but as far as components go i have no idea
