360 year differences

Again, I was pointing out the differences like asked and I didn't say it was the best head I said one of the best heads meaning there are others just as good.


But according to the Mopar engine manual, the intake ports do flow same but the exhaust ports do not because of the hump in them for the AIR port. Granted this can be ground out and made to flow the same as the "J" head and would be a better value but they are not the same as cast. Unless the Mopar manual is wrong.
