Default [NEED INFO QUICK]plug gap on 92 LT1?

I bought some NGK TR55IX Iridium plugs and was wondering what the plug gap should be for best performance? :cheers:

Your plug gap should be .050''. I believe it is stated on your emission label under the hood.

I have the regular TR55's. Gapped them at .050. You should have to close them a bit from the factory NGK setting.
