Thanks. But just to be clear, Ken Parkman did the design work on the heads while I designed the fixtures and did the machining.

They are a canted, rotated valve symmetric port design - as any unlimited race design pushrod has gravitated to - for an AMC.
AFIK the first symmetric port canted valve head was the 429 Ford then the Boss/Cleveland, but other than the fundamental configuration pretty much everything is different. The difficult part is adapting it to a bolt pattern and pushrod configuration intended for a siamese port port head. Ford had it easy as they were designing the whole engine; here I had to make the port configuration fit an exhaust side bolt pattern that is different at 3 of the 4 cylinders. That was a challenge! And things like getting the rocker to pushrod angle to vary less than .5 degree through its travel. I'm a little bias, but I like my solutions better than stuff like the Mopar Predator or the Visner stuff.
