I have no idea if items like Coolant System Flush have a negative effect on LS1s, but I've stopped using them because they ate up three water pumps in a Honda I had. I changed the coolant in June, and in August I replaced the pump. Like I said, there may be no problem with LS1's, but I thought you might want a heads up about the possibility.

The service manual says to use only water, for a flush it says just to cycle water through the system until it comes out clear (that is drain and refill with water several times). It say NOT to use a chemical flush.
