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

I'm really mixed up the original OP states 290 CFM.
Didn't Blueprint have a Trick Flow version crate engine at one time.
I think producing another head producing only 260 cfm is an underachieving endeavor. imo but it's not my business or money

I wonder what the trick flow's, flow before there cnc'd ?
Probably around the same as were talking about here (240-260 cfm).
