I assume you mean to inquire whether an M50 head will fit on an M52 short block, as a long block would already have a head.
Terminology aside, I know the pistons are different, but the bore should be the same. And given that the motor will be built, anyway, you'll be replacing the pistons, rods, and maybe the crankshaft...so that little facet wouldn't matter. Heck, I'd try it
