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

Thank you all for the suggestions. All are appreciated. Please remember goal here is gain some performance while providing you with economically sensible crate engines. It's not to design a 9000 RPM, 900 HP, SB with 13:1 compression that would cost 16K, and we'd sell 5 a year of. If someone wants 800+ HP...we sell Gen III's. Gotta Draw the line somewhere. Some may call it weak, I call it practical. I will note the set here flowing 290 are ported. We'll probably use an as cast version on the current alum head 408, and maybe do a ported set on a bigger one. time will tell. I'm really excited about it. Glad to see the interest!
