supercharged 351w sparkplugs?

I just bought a '90 f150 4x4 351w with a Vortech S/C and an MSD ignition. I am doing some maintaince (I dont think the previous owner did any) and am doing the plugs next. What plugs and gap would work well for me? I have heard that platinum doesnt go well with boost.

Thanks in advance

I'd get copper plugs instead of the platinums. Copper doesn't last long as platinums, but they are a much better conductors and cheap to boot. From working with import turbo charged cars, I found that as far as the plug gap goes, widest gap you can go with out any misfiring at maximum boost had the best proformance.
