Wonder why it took so long for a cylinder head manufacturer to make heads for mopar..... Geez you have to have the correct parts to take advantage of these heads. Chevy/Ford guys know this.
In my mind... I just think this thread was just a hoax, mere name dropping.
No graph of the op's motor and based on a biased combo that would only show that the rule still stands... the classic example of the wrong cam, wrong head, aka... worng combo can cut the balls of potential off with rusty scissors...
It does no service for anyone.
OP...
Just post a shout-out to IMM next time.. and just say you're happy with your heads and your combo ...because it's well-matched and makes good power...then post a graph showing it.
