I know for one new parts are needed for the old cars and they will run faster. In the case of the Mopars, the old 906 heads were 3/8 stems, 2.08 1.74 valves. The Eddys and Mopar come with 2.14 and 1.81 valves and 11/32 stems. So now one has to put in 16 new seats, 16 new guides, and 16 new 3/8 valves. This I disagree with, and suggested the heads out-of-the-box @ +10 (a bargain for any combo) and about $1500 cheaper. The heads have to meet the specs from the year claimed, hence change the aforementioned stuff, and only get +5, probably still a bargain. A move in the right direction. The original configuratiion voiced by some are gone, like Clark Gable, with the wind. And you don't have to run them, just like the rockers. What am I misssing here?

You are not missing anything Jeff.The heads (Edelbrock,Mopar 452) should be allowed.I know for a fact that a Edelbrock head isn't that much more than a "massaged" 906 stock eliminator head,and the Hp "penalty" you suggested is in line.Another head worth looking at is one from a company called 440 Source.They have a exact duplicate of a 915 head that is aluminum.
