What if Koffrll, Indy, Eddie or whoever gave Us a BBM head which combined max wedge ports (standard intakes will fit ) BUT also gave us a W / B1 style valve arrangement that opened on the bore center and a more favorable for flow Valve angle?
How hard would it be? Lets assume you're gonna need B1 style pistons? Maybe less a B1 but maybe more of a Scaled-up W8? 2.30 intake valve and 380+ cfm
I was always vexed by why the aftermarket couldn't fix the 1958 valve angles. Look at all the Cleveland/Windsor/twisted wedge choices the Ford guys have. Look at a set of CHI Clevor heads some time,
Keep the shaft, center up them valves!!
Mopar answered your request except for moving the valves.
Mopar Stage VI CNC ported by Chapman flowed 385cfm with a 2.250" valve
