Although it seems logical for every motor to have an aluminum head, it wouldn't be practical for NHRA. Not every available aftermarket aluminum head retains the factory head specifications as far as volumes and valve sizes are concerned. It's hard to imagine NHRA having to mandate their own approved castings for every combo in SS, whenever they claim to be non-profit for the Sportsmen.

Ignoring that part of it, I would like to see NHRA get rid of the intake/exhaust runner volume limits for the factory castings, then control it with HP (maybe ten HP added from initial HP.) Then you could run the aluminum castings as well, but you would have to retain factory volumes, but no initial HP would be added.
