Re: B21A1 head swap (hizzlehonda)
The only heads that directly bolt to a B21A1 are either another B21, or the B20A (B20A5 here in the states).
Using a B20A head will give you slightly higher compression, and thus a teeensy bit more HP and torque. Make sure you always use the B21 head gasket though.

your b20b is not the same thing as the earlier b20a's and b21a's
