The heads should have A 5.7 cast in on the head gasket side. If so they are the car heads.

They are the 00+ 5.7 head with the new (smooth casting) from GM. If you look on the outside of the head, on the underneath side of the runners you'll see a 5.7 casted on one of them.

GM started using a new casting method that results in smoother port walls/chambers etc.
