Aftermarket/Replacement Cylinder Head Rule Change

What a can of worms they've opened now....
The Edelbrocks, aside from the fact that they're aluminum, are made for 2.02/1.60 valves and 1.46" springs. So many more grey areas have just been created, and for what?? "But I can't find any old castings!" BS!! I'll buy that line for other brands, but for small-block Chevys?? Get off the couch.
Well, now there's another 5G just to keep up. Thanks.

Dart or Engine Quest cast iron replacement style heads would have been the correct choice.

However, I'm guessing that neither of them went to the trouble or expense to submit anything.

Anyone who has been through the NHRA approval wringer for anything will understand, especially if they've had parts rejected for subjective illogical reasons.

Aluminum heads for Super Stock make sense, considering the alterations allowed, and the easier repair of aluminum. For Stock, not so much, they just allow cheaper and easier cheating.
