What spark plugs do you run with gt40-p heads? I have been running Autolite 2544's for two years now. Went into Napa today to get som non resistor types, and they tell me I've been running the wrong ones. The one's I've been running stick into the chamber about 3/16's of an inch further than the ones they gave me (AT 754) Would this be a disadvantage for any reason?

Im not sure on your plugs i run motorcraft aws22c im pretty sure thats the complete number. you could have them cross reference from there. I do know that the gtp heads have a very short threaded ared ( short plug)

Those are 5/8 plugs if memory serves me, I would use a 132 Autolite!
