As I said earlier I would not choose this combination myself for a bracket engine that went this long between being rebuilt or this many runs. I would use the std 1/16" top rings. I did use the Hellfires in one engine and they wore the tops of the cylinders. A 555 with Big Dukes....
I ran .031" Dykes a lot in flat piston small block engines. Typical SS type 350's. That was pretty std. 20 years ago.....I ran those rings very high on the pistons. I think they were .050" down on at least one engine. Never had any problem but I was never able to run with the fast guys back then with my budget.....

You own the green Camaro ED posts the pics of??? If so nice car
We use domed pistons many times, so we cant run the Dykes ring that high but what we do is run it .100 to .200 down depending on dome and valve pockets and turn the upper ring land down so gas pressure can apply the ring
IMO 1/16" is the best damn bracket ring out, 1/16" top, 1/16" Napier Second or Reverse Twist, 3/16" 16 pound oil ring
If I want any more gain from the rings, Dykes, .031"
I do want to try an 1/16" GoldFinish top ring, due to it solving the wear issues with the 043
The GoldFinish is a face coated TNT/Hellfire ring thats lapped too, The GoldFinish 043 is much better than normal 043 rings or AP 043 rings
