1971 340 Build - Choosing piston rings dilemma

Thanks for the input, I have been looking at Total Seal a few times now.

Hastings have a broad range. Their premium Plasma Moly range is over $160 for a set. The higher price seems to be for the ductile iron top ring as opposed to just iron. Then they have phosphate coated for the cheaper ones. I still have not heard what the difference between Plasma Moly and just "Moly" is. Is it a different or better facing process? Or just technical jargon to make things sound like higher quality? I would like to be better informed in this area where there are so many brands and such a high range of prices, for basically a part that all do the same thing. I have a feeling that in the $300 and under range, mostly it all comes down to "Names and Claims". A $900 set of rings for a Top Fuel Dragster would certainly be in a different league of quality.
Dont overthink this... Plasma is the process used to spray the moly on the ring... All the same.

Any high quality ring will work. I have used simple cast rings when the budget was tight even on modern engines.

Years ago we only had chrome or cast. Top fuel cars ran cast back then...went 250 mph!
