considering that the GSR will give you more compresson because of its smaller combustion chamber, i say stick with a C1 head and just give it a slight P+P job. then add whatever cams you want, ITR, Skunk2, Jun 3, VTEC Killers etc.
im sorry guys. we usually agree on alot but this time i have to disagree. if you want to go all motor definately get the itr head or even a b16 head. raise that compression and get those horses.
if you want to later boost it then stick with the gsr head. gsr's love boost.
Hyper are you forgetting something?? Remember, I told you that throwing the B16A pistons into a GSR motor will jump the compression up to 11.4 then you could still add the 2 layer head gasket from spoon or mugen.
Your right Baldy, I meant to say most parts, but not all........
