Thanks to Ed, he was able to de-code my 327. Can someone (maybe Ed :) ) de-code the heads for me?? (#3998993) Are they worth keeping or should I change them?? Thanks. V/r, Don

Per Mortec, they are 72-73 vintage 307/350 heads, with 75 cc chambers. Probably only worth it if you are using domed pistons. I would recommend something with a 64-68 cc chamber for a street engine, perhaps a vortec head if you can afford to go that route.
