I would only consider RFD's heads and whichever head i use i want to compare both at cnc and max porting. I'm mainly trying to figure out if going to a 14, 18 or 12* head would be worth it for me. Keep in mind this is going in 3600lb mud racing truck that only runs 200'. Don't take that wrong cause every truck in my class is a 621+ BBF (with c heads 2.5 valves) or 632 BBC (big chiefs ) making in the 1050+hp range. Our rules limit us to only 1 carb, no tunnel ram or sheet metal intakes. Because of my rule limits will it be worth the extra cost to go to a 500+ cfm spread port head when the RFD 24* edelbrock heads are capable of 1200hp which is more than 1 carb can make anyway????
Thanks
