Default valley cover

i am doing a 5.3 carb setup. is there a valley cover that has the pcv tube and not the knock sensor provisions. I won't need them and the hole will be able to be seen from the front of the motor(i think).

Use an LS2 valley cover, the 5.3L motors have the PVC the valve covers.

The Ls2 uses different knock sensors and they are mounted to the side of the block.
