I gap .040 as well, with NGK racing plugs, R5671A8. Always had good luck with NGK in other applications, and anything with the word "race" next to it just turns me on. Ran with 7 heat range for a spell, but thought they were just a little too hot.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
