Anyone looking for a good pair of Chevy SB 1972 487X heads cores with cast dates A-20-2, A-24-2. These are virgin cores, not ported or milled. Make good heads for a stock eliminator motor. Heads have been cleaned and magged for cracks, all good. Valve sizes are 1.94 Intake and 1.50 Exhaust valves. The 487X Heads also came with 2.02 intake and 1.60 exhaust valves for the 1972 Corvette and Camaro Z-28 models, LT-1 350 Engines. These can be cut for the 2.02 -1.60 valves. They have hardened seats from the factory. I have the factory valves, springs etc in a box which i will throw in if interested. I am asking 75.00 dollars for heads plus shipping to your zip code. Will not ship outside of the USA. Send message if interested and email address and i will send you pictures if you want. Located in Michigan. Do your homework to make sure these are the heads you need if interested.
