I need a recommendation for spark plug gap in my SL. I know that this subject has come up before but I haven't been able to find a recommendation for my particular application. Any help would be appreciated. I will be running RN9YCs at 18-20 psi and I am running an MSD-6A and MSD wires with a Rich Bryant cap. Also, a ported 782, ported 2-piece, ported EM, Taft S2, +40s, 3-bar, 46-trim .63 AR, and fuel pressure at 55 psi. Thanks, David
