Highest flowing sbm heads?

6.4 Hemi, factory 485 "NET" hp. Tell me what that is in our dyno "GROSS" hp please. So we are around 550+ hp ??? bone stock and idling smooth??? Cam swap and good exhaust and we are over 600 hp.
You can "not" like it. You can defy it in our "older vehicles". You can stomp in front of the mirror. But in reality, you cannot get as much hp cheaper with same reliability with a "LA" build. And yes, I'm a realist. Sorry. :)LOL.....I just must be lucky I guess.....I smoked those tanks when I had my little 415" Indy T/A engine.....by a lot!!!! Destroyed the Hell
