I will be putting a set of GT40 heads from a 96 Explorer on my 95gts and was told the plug is different from the E7's. If so can anyone tell me what plug to use?

Thanks. Is that a stock heat range or one step colder?

What is the difference between those and the Autolite 24's or 25's? I bought a set of 25's yesterday for my GT40's (non-P). So will the 25's not work?

25's will not work.

I use NGK Tr6 they are one range colder than stock, Tr5 is the stock gt40 plug you or a shop should be able to cross that, I forgot what the autolite plug #is for the stock heat range.

Damn I'm glad I read the thread time to make a trip back to Checker.
