Many of us use NGKs. For your mods, NGK TR55s would be a good chioce. They are stock heat range. I usually gap them at .055.

Ive run them both..with the NGK TR55IX being the current plug of choice. My car seems to run slightly better with the NGK plugs. I'm happy with them and would/will purchase them again when needed.
