Jeff, The 390 Ford Iron head has a 144 cc intake runner and a 103 exhaust runner. The Edlebrock head has a 173 cc intake and a 123 exhaust and is rated 8 hp more than the iron counterpart. You can find those heads everywhere.
I agree with you, what ever Edlebrock produces as a replacement add HP to it and let the system work. So we as the racers can buy new available, and afordable castings to race with. Plus we can support the people putting money into our sport.
The Ram Air 2 cylinder head castings for the car I run, is Impossible to find. The set on the car cost 2500.00 just for the castings. I'd take 20 HP just to be able to buy them.
NHRA need to be flexible and work with us in allowing some new parts so we can keep racing our cars. Something everybody should fight for that has to purchase rare and expensive castings. Just my 02 cents

A real money saver there. This subject has been somewhat vetted by the Ford guys with the Edlebrock heads. Hawk tried to get the ruling I favor, but I don't think it got done. Maybe they feel better now.
