Promaxx new iron mag heads, good quality

It's amazes me anyone would even bother producing SBM heads in today's world. How much of a market can there really be?

As for Promaxx, I looked at their site briefly, at their 'Shocker CNC' heads for BB Mopars, and they look kinda funny with increasing CFM numbers out to .900 lift. Is anyone running .900 lift cams gonna be using a relatively low flowing BB head?

believe it or not giving cfm numbers to .800-900 although a bit high gives you some good info about the head or the cnc or porting work done. If a head has cnc numbers that continue to climb and not fall on its face it tells you they got their program right. Heck my son is running a cam under .500 lift and I flowed to to .800
