Just build a 408 
Seriously though a 302 head can be made to flow at least 220 and 163 with 1.88 1.60 valves. I have a set that has been CNC ported and that is what they flow at .500.
wow, that's 18CFM better than RyanJ got on the exhaust port of a maxed out 302 IIRC.
so for all that porting, they flow about the same as stock mags, or less than the LA intake pattern enginequest 318B's you can buy new from hughes engines assembled for $725/pr
Hughes Iron Ram heads
as cheap as these are, I can't see spending the money on building used LA heads if they need new valves.
