Hello gentlemen, I am working on a 70 model 350 and have exchanged the old point type distributor for a HEI from who knows what but it has been so long since I have tackled this little chore that I have forgotten what kind of plugs I used to use. I know if I get some that I can gap wider it will be better. The ones in the motor are the 13/16 with the metal gasket that seals them to the head. The guy at the parts store told me that the ones with the 5/8 would work just fine but I would rather get a plug that seals like it is supposed to, not with the beveled seat that the 5/8 plugs have. What I am asking for is a number for say an AC plug that will work with the HEI distributor. Thanks,
