Looks like the intake rules give you a little room for raising the intake roof at the flange. With a max of 0.100" intake gasket will help but may need head shaving to keep with in the rules and get that roof up.
It sure would be nice to have a hand full of heads to experiment with. aka how much can you shave from the head gasket area before you start messing with combustion chamber recovery........ and can you get a way with more shaving on say a 308 or, visa versa.
And a intake to match up with each combo.
So why are you not considering the Emission later heads. Much easier to get ahold of, and cheap.
In a max port affair, is there a HP lose between a 596 casting, 360 head compared to a J head????????
