I need to figure out what gap to set my new plugs at. I installed these today but just screw them in by hand until I get the correct gap numbers. They are going in a 393 with afr 185's. They came gapped anywhere from .038 .041 Thanks in advance.
Originally posted by wazee Thanks, I just got back from racer walsh and eddie told me .050 . Now about torque?? How many foot pounds to you torque spark plugs down in aluminum heads. 15?
just use good judgement and get them snug, there gonna feel semi tight(this is the washer crushing)then theyll start to get snug ive NEVER had a problem with hurting the soft aluminum threads and ive never had a plug back out on me.
