The NHRA will have to allow both the "closed" and "open" chambered heads in either Stock or SS.
And what about my Max Wedge heads?

Sorry for the "All Big Block" I cant say for sure what they will be doing about the Max Wedge yet.
As for the Chamber design, John is correct in that the ED heads and Mopar Heads are closed chamber. As long as you have the correct cc for Year and HP claimed thats all that matters. The design does not dictate the cc.
Hope this helps out!
