Re: spark plug gap
I’ve had great luck with the Accel shorty plugs. I gap my non-HEI system to .035

Re: spark plug gap
I use AC Delco R44TS gapped at .045" with HEI. If you have points, gap your plugs at .035"

Re: spark plug gap
with the HEI's you can go with quite a large gap. it will be hard starting at higher altitudes and with cheap gas.
