If anyone wants the part numbers they are:

R5724-8
7317 (stock number)

They come pre-gapped at .022. I do not know what they are OEM for.

I would NOT run these unless you gonna run a lot of boost, like over 18-20 psi. Until then TR6's should be fine.

Just an FYI to those who were curious.

cool thanks for the info. I bet those suckers will foul pretty easily

Are you positive those are a resistor plug? I don't have a NGK catalog handy, but I seem to remember they weren't?

I ran non resistor champion s57c back when I was on the bottle. Cut back and non projected nose plugs.
Very cold plugs and would foul quickly on the street.
However, no resistors in the plugs had no issues with the pcm or even the radio while using stock plug wires.

I don't know Chris.

Steve I think I can lean out the idle and part throttle to get the plugs to work a bit on the street.

I run these plugs and so do Slomaro and another one of my friends with LS1's.
