Highest flowing sbm heads?

Another one of these days I’m going to run this engine. Shop art just like my blue duster. Lol

that build really did what Valley wanted it to. Won a competition and put his shop on the map. His business has real grown last several years.
Anything else is just gravy. That said, when he finds time he enjoys racing, he is a pretty good racer.
Mopar guy too!
