spark plug gap?

ok, before i put my plugs back in i want to make sure the gaps are ok. Im running the ngk tr55 iridium plugs. what is the gap supposed to be? They are at .060 right now and i've seen anything from .044 to .060

Thanks for the help

based on your mods i would run .050 to .055
but first verify if you should change this particular plug(iridium).

thats no answer-I know

I would go to the ngk web site to find the proper gag for your plugs.

I spoke to Brandon @ NGK and he does not reccomend the Tr55 for the LS1, he advises TR6 or TR5 gapped at 35-38 for modified engines at 11:00 compression and higher. .

FYI

just curious, any reason behind that. If you go to their site, one of the plugs are the tr55 that come up when searching for the vette plugs.
