Hi All,
Just had to clean up some mildly-fouled plugs (old gas and lot's of idling), and thought I'd regap them.
Reading through this site, I see many, many different suggested gaps. I read that with MSD boxes, gap should be changed. I also read that a test of different gaps had no resultant change in HP.
So, there's a lot of variation for perhaps not much outcome.
So, I turn this to you all for your opinions.
I've been gapping my plugs at .030
I've got a 10.4:1 505" RB with E'brock heads, a 0.587/0.593 287/294 cam, M1 intake and 1050 Dominator.
MSD 6AL box, MSD Blaster 2 coil, MP distributor and NGK BCP6ES plugs.
For street and strip, what would you gap them at?

Cheers!
