Not belittling anyone here, but all my chevy friends laugh at the mopar head flows, even after reworking them . I had that much w/ a cheap set of holley alum. heads that we reworked !
And compared to a rat head----------------
And cylinder heads (flow) has always been a short coming for us MoPar guys. The Chevy guys can get a head flowing what we consider outrageous flow numbers very easy as there actual a common and easy to get head for them. And way cheaper.
