    Points should be fine. It comes up as a small engine, lawn-mower, type plug when you search.

    The one problem I have is. I have an actual GM HEI built for my engine. I need to find the equivalent plug that would work for an HEI in my 308 engine.

    I have been running a GM HEI and all of my general motors vehicles starting with my 1968 Oldsmobile 442. I had the second generation 400 in my engine.

    HEI won't care, you just need to observe what gap it likes. Just a little bit of test and tune.  Start with a 'average' GM HEI spark gap and go from there.

    So the suggested spark plugs will work with my set up

    Try a gap of .045- .050 and see how it runs.
