So I just had a chance to look at them. There are 2 sets of small numbers cast into the bottom of the heads. The first set is 6 7 8 9 10. The second set is 05010 the numbers are the same on both heads. What year were they made? I actually think these heads are brand new and never run. They were on a 1960 Corvette show car that never had the engine started. As for the ports I wouldn't say they are ported. A light radius was added to make them match the stock intake gasket. I will post some pics in a few minutes.
