It really doesn't matter unless your buying pistons and connecting rods. Or other similar major parts. The stamp on the block is almost impossible to see with it in the truck. You could take the valve covers off and look up the head casting numbers. Heads are interchangeable but it may help

the pad on the front of the motor to the left of the water pump..look for the letters 2 or 3 of them after the numbers..
