The gap should be between .032 ~ .035 for stock ignition. If you have a modified (HEI or MSD type) you can easily got to .040.

Thank you, stock ignition. Wow, very tight fit, headman headers are make getting plugs out a nightmare. Found a couple of them previous owner put in only finger tight. Now I know why. Thank you

It depends on if it's electronic or points. If it's electronic your gap can be larger like 34 if it's points around 28 but that's from memory.

My HEI is between 50 & 55 .... But he says it's a stock ignition so follow the above advice.
