Race Hemi Piston Rings?

LOOKS like TRW 12.5 , BEST I can see in the pic. ???
The old dykes rings work and work well. They just don`t last as long. You could always have a competent machine shop cut those heavy pistons for any ring u want. I`d have them lightened as much as safely possible.

Yes, old Mopar slugs are TRW all wright.
Also having second thoughts when it comes to all the machine job they need, but 790g less pin, is not a bad start.
Barton have nice pistons for a resonable price. What do you say?
Thanks for your advise.
