NGK GR5 gap size with MSD 6 Box

[RichardJ916]

I just picked up a set of NGK V-Power GR5 plugs, great deal ( Free ) and was wondering if they are good plugs and if they will work what with current MSD Box what should I set the cap at....
360 Street Build....

Thanks

Should be on msd website but I believe it's .040 or .060 gap

I run mine in the Demon at .045" plus run the MSD coil as well. All the gap in the world won't help is there is not enough juice to jump it.
