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...

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