Funny how I was just looking into what would be a good plug for my ap.
Running fresh twin ford 302's... Edl. alum heads. Edl performer intake, 650 speed demons, MSD-6A Ign box's and MSD Blaster Coil and MDS dist.
I'm 30 over on the cyl and Compression is about 9.5
36-38deg max on the timing and it comes in quick.
I think my plugs may be too cool or does it matter at all since I have the MSD boxes?
Any thoughts?

Run the coldest you can, if they foul, move them 1 hotter. Test and repeat!
