I have a 88 e28 528e. Just wondering if an m30 head will fit a m20. Thanks

Nope, not even close. An absolute no.

Actually, it depends on your definition of fit.

It also depends on whether you are willing to melt it down and re-cast and machine it it first (you'll have to do this with the head and not the block; there won't be enough metal in the M20 block to make an M30 block).
