Magnum heads from Dragway Tools?

I can't find the thread, but a member here, I think RAMM, one of the engine builders/machinists/cyl head guys on this site flowed a set. They didn't flow as well as stock magnums, extremely rough castings, not a performance oriented piece was the tone of his writeup. I don't believe he ported them, and used them in a stock replacement type situation on a truck engine.
