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

Here's the deal....
You can change the intake side and simply use a magnum styled exhaust port. The iron sm mag exhaust ports are really nice..and use a regular readily available header. The intake... who would bolt an ootb aluminum intake onto a 300 cm head it wasn't designed for? I don't know of anyone who would, knowingly. All the intake out there were designed around stock heads...the flow low stock 200's cfm. Come on man...
I'm sure one could be made to at least make the push rod pinch thicker toward the push rod maybe another .060. Look at the push rods lean in these things to the side.
So a stock constraint magnum port doing 300+cfm., that guinea pig is going to be 70% iron and 30% epoxy.
