225 Hemi head
Back in the 60's and 70's, Comp racers cut and spliced all sorts of V8 heads to work on straight Six engines. I would guess...and I don't have any examples handy to actually check...but if someone was really creative and had good fabrication skills, that an early Dodge or Desoto Hemi head would have close enough bore spacing and head bolt patterns that it could be made to work.
