Nope.
The aftermarket cylinder head needs to be approved by NHRA and added to the list of NHRA accepted products. No billet heads allowed although there are rumors of some billet heads in use that have been made to look like a casting.
It took me close to a year to get an Edelbrock cylinder head approved.
