Any one know anything about these heads? 2.08/1.60 valves, 185cc runners, 65cc chambers. Promax claims over 285cfm.

First, I have zero experience with small block mopars. I have a 273 2bbl, but I have done nothing with it.
That said, from what I know of Promaxx and the people that own it, I would give their heads a shot. I am somewhat skeptical about the 285 cfm.
I would consult Pittsburg Racer, and Porter racing heads (PRH) for an expert opinion.

I have not personally owned them, but have a friend that did use them. Nice heads. Here they are on a stroker in a all steel truck.
Retailers are asking Trick Flow prices for them.
I looked at them but the price is so close to trick flow which flow a real 300 (Per Weingartner) out of the box and have a better shaped chamber that it made going with TF a easy choice (if you have 4 months to wait for a pair)
Priced the same, I'd go with TF. If for no other reason, resale and worth.

There is a thread on them from one of the Canadian members.
Pics, flow numbers, etc.
