Buy a set of SR Max Wedge port size heads and run them up twocents
There is a local 1964 dodge 330 bracket car running those heads on his 440 short block with headers and non stock carbs, it runs good work
I raced a 1963 415 HP M.W. in NHRA stock for many years ending in 1988, the better heads make more power and run better also up

Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
