i'd stick with the b16a head. the labor put in isn't worth the return.
He never got the b16 head thats why he gave me the gsr head. so should I be a dick and tell the guy to get me the sir head
or should I just save me the trouble of being another month without my car?
and yeah I'm planning to boost it in the next couple of months.
