I want to say 40 gap. Dont quote me on that though. Cant remember because I always gap mine 5 over factory specs. I'm sure somebody will chime in but if you in a rush just go to your local parts store you frequent and they will be able to tell you. Heck if your like me you just walk in and get on the computer. They get mad when I ask for help. LOL

back in 73 the plugs were gapped at 35 but that was with a point system and they weren't using the heads your using. I would check what heads they are and use the plugs according to years for those heads...

.060 is common for a low compression motor with HEI and EGR.
