what kind of head could i put on my 1.5l head what kind of options do i have to make more hps and could i put a old 2.1 dohc prelude head on a 1.5l bottom end is that possible if you could give me tips that would be cool

 

dont think so....i would say you can only swap heads in the same series of motors such as the B, D,H and K im sure there are exceptions but i would use that as a general rule....i guess the sky is the limit tho
