What is the big difference between the B18a , b , and c... I know thw horse power and torque.. Is block tthe same which is best?? I have a B18a1 in crx now can you swap heads for a little more power or higher compression..

 

if you were to do a head swap, only one id do is an lsv head swap.

power differences yes, also there is VTEC heads VS non VTEC heads.
