I know there has to be more than 5 guys that are running these heads.
When I talked to the Trick Flow guys at Norwalk 4-5 years ago I told them that the big block Mopar market was pretty flooded and there was more need for a GOOD small block head. He asked if his Friends could join the conversation and 5 of us sat there for 30 minutes BSing. Several of the employees thought the same thing but it was to far along to do anything about it. They will sell some heads but there are only so many big block Mopar guys.
