IMHO, if the aftermarket head (carrying a +10 factor) gets a HP hit then yes, it should affect the stock head.

The point of my side of this conversation is that whatever the "stock head" HP factor is, the "aftermarket head" factor should be +10!

These "aftermarket" heads were not handed out to be of any advantage other than that of access to the Racer. If the Racer chooses to take advantage of the ease of access provided by the "aftermarket" head then the Racer should be willing to accept the +10 HP/weight penalty.

I agree 100% with you. All of a sudden there were all these new combos born over night!
How about the stock heads make one natural class but the aftermarket headed combos change the natural class.

Oh and add in the combos that give you 2 carb options and 2 different hp factors then add in aftermarket heads!

6 different combos out of one original combo!
