Tom,

On most FE engines, the D/M/Y code is also stamped on the tops of the heads under the valve covers. They are normally easier to read and that is where I finally found mine. If they are the heads that came with the block then they should match. After looking there, I could see the ones on the block were the same, just very difficult to really be sure of as I didn't have the engine out of the car.
