I saw this on Bobs it is a copy of the old Honda head and Mike from cloneenginepartsonline.com has them for sale. While I still like the hemi it lacks a squish area unless welded which causes other issues. This head has two squish areas and a sort of fast burn design with tapered walls. This allows a good amount of CC reduction without excessive milling. I am going to baseline this head on the bench and take molds of the ports then make a big valve (32/25) head out of it and retest.
