Don't know about anybody else, but very interesting to me indeed! Reminds me of when I used to build in-line four drag bikes, I built two cylinder heads for a 1327cc GS Suzuki, one epoxied dump port style, and one tumble port. They each had their strengths, but the best head ended up being a hybrid of the two.

My next cylinder head project is a set of Stealths. A preliminary look reveals significant chamber shift, with some valves much more shrouded than others. Sounds like these are a prime candidate to duplicate your science experiment!
