I know the cams are different, but is their anything else? Are the port sizes the same? Reason being, I have a B18A1 head I do not need and my brother in law has a 94 LS. he would like to get some head work done and put it on his 94 LS.
#1, get head work done on the 1994 LS, it already makes 12 more hp, so it will make more. if u do headwork on the 1990 LS is wont make as much Hp as the 1994 LS head. the ports are the same, the b18b head just flows better and his better cams.
