One of my real "pet peeves" in Stock is this whole "aftermarket" aluminum cylinder head deal. When this was "sold" to us ( "us" meaning all Stock Racers, not just those who actually have access to "aftermarket" aluminum cylinder heads), it was "sold" to us under the premise that if an "aftermarket" aluminum cylinder head was used it was with a 10 HP penalty over the OEM head. What happened to that? The way this deal is right now, the OEM head and the "aftermarket" aluminum cylinder head are considered two COMPLETELY different combos by NHRA with their own AHFS factors! Right now, certain "aftermarket" aluminum head MOPAR combos are factored less than the OEM head combo!
I think that it's time to get back to reality here and either do away with the "aftermarket" aluminum heads and stop discriminating against those Racers who don't have access to them or go back to the original intent of the "rule". The OEM and "aftermarket" head should be considered one combo by the AHFS and if the "aftermarket" head gets an AHFS hit then the OEM head takes the hit and the "aftermarket" head is +10.

Billy,
Why +10? Didn't we just talk about this in another thread?

Thats what I was referring to.
The Mopar alum head looks to be the best candidate to me, but I dont see any reason to use them with a 60# weight penalty.
There is no performance gain, possibly a loss by putting the same port design in an aluminum head.
