Volvo 240 head - what engine does this fit?

[Greg]

Hi folks!

I have a reconditioned head for a Volvo engine that I eventually want
to sell. I know it fits a B21 (fuel-injected) engine. That being the
case, will it definitely fit any other engines? (Like B230, B23, or
anything else I can't think of?)

Thanks for reading.

Greg.
