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

I think Johnny is just barking up a tree.
you would need custom headers, probably intake, and rocker gear( when I say custom, I mean non factory style)
What doing all this stuff equals, is an Indy head, which is already available

There would be no reason for a custom or non factory intake or headers. Not sure why you keep repeating that. For rocker gear, even if the head were to stick with chevy rockers offset intakes are availible up to .775 and in a shaft form. All this does not have to equal an indy and can come in at half the price.
