So running with 6 quarts should only be 1/2 over?
And psychocabbage: I don't think you check ENGINE oil with the motor running............that's only for checking auto-tranny fluid (unless there's something I'm missing..........but how would you get an accurate measurement otherwise?

. Off hand, what's the distance between the "ADD" and the "FULL" mark......1"? So based on the fact that it's roughly 1 quart to get from the ADD to the FULL mark, then going 1/2" above full, would be about 1/2 quart above full, right? IMO, that's OK, but not really necessary.

As far as how to check your oil level.
Go out to your car and open the glove box and pull out the owners manual. Then READ it. There is a very specific procedure for checking the oil level in an LS1 motor. And it's not the same as we're used to doing. I won't try to quote it because if I get 1 word wrong you'll flame me.
Over filling the oil does 2 things:
1. It can put oil against seals and gaskets that weren't designed to hold back oil constantly. They're designed to hold back splashed oil only.
2. And by far the most important. Too high of an oil level will (as another has stated) allow the throws of the crankshaft to beat thru the oil. This action will aerate the oil which causes loss of oil pressure (air is easier to compress) and loss of lubrication of the bearing surfaces (air doesn't lubricate).
Depending on the engine and the type of usage sometimes extra oil is the lesser of 2 evils if you don't want to make the permanent changes to the oiling system that severe racing environments can require.
The best thing for the average Joe to do is to keep the level where the manual states. So if you use a bigger filter as I do then it takes more oil to maintain the correct level. It doesn't hurt anything as long as the oil level is kept in the proper running range. Again as stated in the manual.
