We like to let ours sit overnight with the cleaner in it so it can really break down the carbon good.
I might just do that. Thanks for the advice man.
BTW, my cam arrived today

This is after a drive to school and letting it sit about 2 hrs while taking a final. This is what GM calls normal noise. It doesn't burn any oil or anything like that, still runs great. Just makes a god awful noise.

That is a tick not a knock.If the pushrods were .020 longer it might cure it.My 6.0 with the heads shaved .020 is more quiet than the stock 5.3.A little tighter preload on the lifters would make the difference.
