setting the timing on a 01 silverado 4.8

[blackedoutsierra03]

I have a 01 silverado that the lifters failed and im replacing all the liffters and pulling the cam to make sure it hasnt wiped a lobe, how would I set the timing back on the truck?

No timing to set. Mark the sprockets when removing. Timing is all computer controlled.
