Other than the obvious obd2-obdo, would it be cool to put a b1 head on a1 block? Or would it be wise to just stick with a b18a1 head? I dont see why it would matter, but I just wanna make sure. Would I get the 10hp im missing by using the b1 too? Thanks.

 

i think the only difference is the cams and porting.. u should gain hp
