    Is there any specific difference between a b18a1 head and a b18b1 head? I eventually want to use a b1 head on my a1 block-- warpage issues.

    The B18B1 has a better-flowing intake manifold and slightly more aggressive cams, so yeah, it's bolt on and it would be a slight upgrade...

    Well, the 90-91 B18A1 only made 130 horses, so if that's what he's starting with then it's a more significant upgrade...

    10 is pretty nice. quite noticeable.
    Would he have to change anything else out aside from a possible timing adjustment?
