Unless it is blown, turboed or uses nitrous, I would be going hotter, not colder.

First off why do you feel you need a colder plug?
Can you post up a picture of a few of them?

If you have determined you need colder plugs that fit those heads, PM me. I have several Champion race plug numbers that are colder than that NGK part number. Including some contour and fine wire options. They are in the 57 and 55 heat ranges. Have lots of them and would like to liquidate.
