I just picked up a B20b and will be using it with my Ls head. Does anyone have any suggestions on the type of pistons i should get. I want the compression to be around 11.1, because my car is driven all year round.

I am using custom 12:5:1 JE's with reliefs that will accomadate the narrower B18B valves or the slightly broader B16 valves

 

I got the b20b roller waves for a b20w/ b16a head. Haven't installed yet. They look good though.
