Spark plug gapping I was an idiot and didn't check before I started and did it at a buddies house without the net.. We kinda winged it and took a guess..
I gapped them at 32.. They are NGK Tr-6s. I will be spraying a 75-175 shot.
Will I be ok or do I need to take them out and change the gap?

Damn it.. I have always heard Tr6s will be fine on a H/C ls1 with anything up to a 200 shot..
Can I pick up a set of the Br7s at autozone (anybody got a price estimate/part number)..

With your motor and the pistons that are in it you are probably o.k. with a #6, but I always air on the side of caution.
Get some heads on that thing to bump the compression back in the high 11 range and between the compression and the heads, probably pick up 60 rwhp.
