Anyone come into contact with these castings offered by MP for a short time and then mysteriously disappeared?-They were part #P4532796 available in year 2000 from Mopar Performance and also sold by Indy's store called Aerohead. These heads offered stage VI port volumes, but the intake ports were not raised like the original Stage VI and therefore accepted the standard intake for B/RB aplications (instead of needing a RB intake on a B block, or spacers on a RB block) Where they so bad they got pulled within a year? I purchased a pair from Aerohead and had to fix the butcher port job they charged me for, when it was all said and done one head was set up on a superflow at a local head shop. The heads put up 317 cfm intake and 205 cfm exhaust at .550- they pretty much flattened out after that. I don't know how those numbers compare to a ported set of 906's, but they seem reasonable. I Just hope that there wasn't other issues at work- ie casting porosity.
