Re: NHRA allows Alum heads in stock/ss
I`m not sure if all the Edelbrock heads have no exhaust crossover passage or not, but I know many do. Yet with a factory head, you are not allowed to plug the crossover into the bowl area. Also, I`m pretty sure that not all the new heads approved use the same combustion chamber volume or valve sizes for every application that they are approved for. Interesting, eh?
