Making Aluminum Heads Legal for all SuperStockers

In the last 3 years, we've bought 4-5 sets of 401 casting GMPP big block NHRA legal aluminum heads. And 3-4 sets of Edelbrock NHRA legal FE Ford heads. And a set of the Oldsmobile Edelbrock heads. They are all within $200 in cost, per pair. Sorry Jim, you're absolutely wrong, period. You can only buy the GMPP 401 head from a GMPP dealer, such as Pace or Scoggin Dickey. You can buy the Edelbrock NHRA legal heads from anyone who sells Edelbrock.

And BSA 633 is right, if you use the GMPP 401 head to replace the old cast iron closed chamber head, it requires $2000 worth of work, including reaming the guides, angle milling the head, spot facing the bolt holes, and correcting the angle on the intake flange.

And I'm NOT advocating opening up the rules to allow more aftermarket stuff in Stock or Super Stock. All I'm doing here is correcting some seriously incorrect information.

Alan,

These figures are from Jegs for NHRA accepted for a set of bare heads: BBP..$1512.00; BBO..$ 1534.00; BBF..$1200.00. I went to the Scoggins site and could not find a listing for a 401 head but found a 410 bare head at $ 1500.00. The price for a set of legal BBM heads will be in the $ 5000.00 to $10,000.00 range because they would have to be tooled and produced....no one make anything near legal at this time ( this estimate from Indy heads for first run).

Couldn't find figures on AMC or any of the other small block combinations out there .....what do they do while everyone else gets aluminum heads?

I stand corrected about the chevy BB heads, it looks like the price is about the same for a bare head.
