If the head in question casting number is listed in the blue print specs it is a legal head to run.
Just because there is no runner volumes published doesn’t matter. It is not racers responsibility to publish them. It’s NHRA job. They gave you a list of legal heads to run and it’s there job to publish specs on head. RJ |
