The valve sizes bugged me, so I looked up the Cleveland 4V heads. They are 2.19"/1.71" and the Chrysler Hemi Heads from the 1960's are 2.25"/1.94".

Also at first glance I realized these are not a true Hemi head. However when I looked more closely these are far from a Hemi head. I'm not sure they are deep enough to require a domed piston. They quoted a chamber CC that sounds like you could use a flat top piston.

Now that said, the Hemi head design has its problems. So maybe they solved a lot of problems with this design. However I'm not sure they will outperform a set of CHI heads.
