360 spark plugs for racing?

I use NGK R5671A-8 in my small block. I would try either a -7 (which is a little hotter) or a -8 plug.

Thank you. I forgot, it is .030 over w/ flat tops. Nice color on the Fish by the way. Did you race at the Bracket Finals last year? I made it down to 16 cars w/ the Dart.
