I have an Edelbrock Performer RPM head, gonna use an autolite plug. I think the heat ranges are 24, 25 and 26, does that sound right? The parts guy gave me the medium heat one I think. Its Autolite part# AP3923 Platinum.
Anybody know if this is the right plug? I`m a little worried about letting some dude working behind a parts counter select my heat range, expecially when I know NOTHING about it.
