I'll check my Repro Fentons from Patricks that I recieved a while back. They're not mounted yet. Check them against the Military 302 intake and the "H" head intake flanges that I have. The Patricks Fentons that I got from Patricks have been machined on already, so maybe they prepped the raw Casting to match the old intakes or maybe it was just to fit a GMC engine. Will post pics tonight. Jim
