Suggestions for new design Aluminum Mopar SB clean slate (kind of) cylinder heads

I always wondered how something like this would go on a Mopar? Course, you'd have to go to a stud mounted rocker, but the canted valve design would probably work well. They never caught on good, but I think that's cause guys were scared of um. These are for the small Chevy.

Is that a TF twisted wedge head? Is so, do that thing was horrible. It took a bunch of work just to get it decent.

The first set I did was right after I got my flow bench. I fixed them and all the rail birds were sure I butchered them.

Couldn’t get him to go to the dyno by he picked up 3 tenths.

IIRC that was the head was had an 18 degree angle on the intake valve and 23 on the exhaust.

They didn’t do well because they just weren’t that good.
