Swapping B18a head toa b18b

Hey, long story on why I wanna do this, but anyone know if a b18a head will direct-swap onto a b18b block? I don't wanna haveto do any drilling or anything at this point b.c I'm gonna do that later on b.c I wanna Ls/Vtec.

Thanks much

They are exactly the same except for the cams and intake manifold, but the B18B has better cams and intake manifold. So to directly answer your questio yes it will bolt on with out any drilling etc.

just get the cams
