Weird, over at team camaro i asked about this kind of question and they all said over there that .050 would be a good gap. I actually had them gapped at .035 and putting them at .050 cleaned up the motor nicely.
Edit: Here is the thread over there:

Weird how the same question is answered so different. Maybe its just me. I am going to go read it all again to see if i missed something.
