There are no numbers on the casting pad near the top of the valve covers like all the aluminum heads. There is a long number near the exhaust port that is lightly etched in. I will look as soon as I get home. I do know that they are the exact same casting as the 317's except iron. The iron heads will handle much more boost, but do hold in a little more heat.
