I've used Bosch, Denso (stock from GM), NGK, and Autolite. They all worked.
Just so they're the right heat range you have them and they were free. Throw them in and see how they run. If they run rough, pull and replace with another

Just installed the Bosch Ir's last week, replacing the stock AC Delco. Had the Bosch plugs and wires laying around, so I thru them in. Not bad. But I am switching to NGK TRT55s once I get my headers. The Bosch are comparable to AC Delco. But I still prefer NGK TR55s and MSD wires.
LS1s don't use a waste spark ignition, which is where the shitty Bosch reputation comes from. They DO NOT work in waste spark systems. However, this does not mean it's OK to run them in other applications. They're overpriced and poorly designed. You can find better for cheaper.
