.080" isn't a guarantee you'll have failures, but there was a reason GM recanted that .080" gap. Wasn't for health reasons, I'm sure. I've been setting at .040" with absolutely no issues now for a long time.
GM trainer told me they went to .080 because they could

my father was used to old style points ign and he was helping me with a no spark problem on my 76 olds, so he grabbed the end of the spark plug wire and told me to crank it and rev it up a bit. it knocked him on his butt across the yard and taught me a few new swear words i hadn't thought up in a while. we all had a good laugh about it except him.

I usually test an HEI by setting it up on my bench and spinning the shaft by hand. I always get a robust blue spark. Just for fun I like to slowly increase the gap from the coil button to my ground and see how far it will fire. At one foot the spark is like a lightning bolt and I begin to fear it will choose me as the ground so I stop there. My point is the spark gets stronger the farther the ground is from the coil. The HEI coil is capable of incredible voltage and I have never had firing issues using .060" plug gaps on all my low compression motors. Of course compression, fuel/air ratio, etc all play a part but my totally stock engines are always set at .060" with no issues.

I would appreciate if you did some research on that and let us know about your conclusions, or concussions.....:)

my father was leaning across the fender at the time and got a shrinky winky.
GM instructor did same thing on a metal bench and had everyone lean in to take a look at what he was doing
