My BM's sound great too because they aren't moving the air they are supposed to either. 230 @ .400" is terrible (there's that molested S.S. again.) 260 @ .500" is not good at all for a head of this pedigree (this is when the **** port design begins to show it's true nature)Well executed W2's are around 280-285 @ .500" and they make great power with teeny cams. The "impressive" high lift flow numbers are because the S.S. is layed down (murdered/removed/obliterated) so bloody far.
The exhaust is excellent which is why you are at the mercy of MEGA reversion. All that exhaust is going right back into the intake because "forward" movement of the intake charge is LAZY on account of the f'd intake tract.
I don't know Tom but I bet he's a nice guy and doesn't have skin in the game on this one and that's why he gave you a thumbs up.
The ports better be identical 'cuz they're CNC'd!! This is one of the biggest advantages of CNC anything-CONSISTENCY.
I think you are battling two things here and a nice term would be "tolerance stack" I don't like your cam all that much. I also think your heads would do what you want if you added 2 points static compression, .750-.770" lift single pattern cam, with a header that has no larger than a 3" collector.
I'll say it again--600 REAL HP , out of a (***) ci Small Mopar , Non W head and pumpgas is VERY VERY difficult. Not sh..ng on you just trying to eliminate tail chasing . By the way--thanks for getting the heads tested, It shows me you are serious. J.Rob
