You have to have the head upside down to see the casting numbers. GT-40 heads will have GT cast in them as well as GT-40P's will have GT40P cast in them.

so the numbers are unable to be seen unless the heads are completely off the motor... Guess that will be my next move..

the actual casting numbers are like lxman said on the bottom side of the head by the pushrod holes.
