I'm using Champion 685 race plugs. Works great.

I also tried the Ford AWSF A12C, 2 heat ranges colder than stock, but they are a short thread plug which I shouldn't have used. I have SVO heads which require a full threaded plug. People have used these in factory heads without problems as far as I know. I did make 315rwhp with them at 5psi though.
