DON’T BE FOOLED!

Mopar guys are also a bunch of cheap bastids. Unlike them, I ain't cheap. I'm broke. Plus, they don't offer a slant 6 head. So there's that.
If you or someone on the board has a junk slant 6 head laying around, I can model something up on the computer that would get you to the point that a machine shop could make it. With modern 5 axis, I suspect I could do it from billet with no castings.
