I run a very similar combo and I'm using ngk r plugs gapped at .030". Works very well for me, I've put around 10k street miles and 2 full seasons at the track with no problems on 12 psi.

Whats the heat range number?
Actually, can you just share the whole plug number?

Thanks - Jesse

I was incorrect they're the NGK R TR6's. I got two heat ranges colder than a stock plug when I ordered them I believe they're the 08's.
