Default Spark plug gap recomendations

Please advise I'm running an 03Z with a vortec kit s-trim with 7psi and LG longtubes. I bought new plugs and need to know what to set the gap to.

Man I bet changing plugs on your car sucks worse than mine.

I am not sure what it is like to get to yours....although I have had other kits too..including full length headers, S/C kit, and another type of TT kit (check sig pics). I have never fouled any plugs but will change them occasionally when I feel like it (the times I have changed them I questioned why after I removed a plug...because they still looked good). However when I do it takes 1 hour from start to finish (its been explained in detail on other threads). I think it was about the same when I had full length Stainless Works Headers....they took longer then one of my setups where I was using TPIS LTs. To summarize my current setup, they are pretty easy in contrast to the appearance. You are welcome for the plug gap recommendation.
