Aftermarket/Replacement Cylinder Head Rule Change
Any News as to how the HP factors will be effected with the new rules combining them with OEM heads?

Re: Aftermarket/Replacement Cylinder Head Rule Change
Where are you seeing the aftermarket head rule I am missing something ? I know several combos allow them but I didn't see any new rule about them

Re: Aftermarket/Replacement Cylinder Head Rule Change
Its coming out with the HP releases next week. NHRA is deleting all the different HP factors and combining them all in to one factor for each combo that has approved aftermarket heads.
I was wondering if anyone knew how they were going to determine the new "single HP factor" where the OME head was rated higher than the aftermarket head HP factor and vice-a versa? |

Just say "no".....to aftermarket heads.

Re: Aftermarket/Replacement Cylinder Head Rule Change
I could be wrong but I don't think it is practical to use the Edelbrock head on the Max Wedge, the port mismatch would be quite a challenge since you cant enlarge the ports. If they raise the iron head HP to the aluminum head HP the factor would be higher than the original.
