I have a couple sets of std 717hp HC heads laying around. Would like to know the flow characteristics of a 6.2 HC head vs the 6.4 Apachie head if anyone has that.
Thanks, Jim

Intake has a different bolt pattern on the Hellcat heads. Closest thing to a Hellcat head is a Big Gas Engine aka; BGE heads found on the Ram 6.4 engines. Best head out there for the 6.4 when boosting.
