The autolite ar94 would be like a tr8 ngk if they made one. The ngk number is 5724-8. HOWEVER, the are a non supressor plug so it would be a try it and see approach.

I however run the 103 for the street and the 3932 for race gas.

Think Harlan ran TR6s deep into the 8's. I used them for awhile but I liked the Autolite edge spark plugs more so I stuck with those. Car ran the same 150 mph at 14 lbs of boost no matter what plug was in there. I never tried the tr6s on 20 lbs.

The ls1-2-3-6-7-9 combustion chamber is much more advanced compared to the buick chambers. Its a design that isnt much different that the '64 buick v6 special. On 15 psi tr6 are fine but high boost, melt.

Platinum and iridium seem to preignite on our cars.
