Highest flowing sbm heads?

I think it’s more the older guys like the older stuff. We grew up with it, choose to spend our hard earned money on it, and our friends feel the same way.
Nobody is saying the gen 3 isn’t an excellent piece.
I would rather have my 69 Dart to drive around and race, than I would a Hellcat, and it isn’t even remotely close.
Some people feel differently, and that is fine with me, I am glad the hobby is staying viable
I too am old school. Very old school, just look at my builds.. LOL. However, I'm a realist. I have no issue accepting reality. If I choose that route or not, I'm not afraid to acknowledge it. And although I'm not "hemi swapp'n" anything of mine today, for the sake of the OP I brought up the New Hemi's and their heads. We cannot ignore how fast those heavy pigs can be box-stock off the showroom floor. And with mods, they can be crazy fast, especially when swapped in a under 3000 lbs car.
