Happy Sunday all!

Doing a ton of homework and planing for my super stock 1970 mustang. I have a question in reguards to heads. I am a little confused because It shows that the AFR1399 heads are accepted replacements in the technical bulletins however not in the NHRA accepted replacements. Also in the rulebook it’s a little unclear as to if they are ok to use for super stock. Anyone have experience with this? I do have the matching D00E heads and block for the car and a roller 302 that I could use for GT class. Any help is appreciated.

Thanks!
Chris
