I think they should work great,my brother has been running them for years in his 360 bouncing off the limiter at 7k.,only failures Ive heard of was due to improper ring gap and use of alot of nitrous.
This is only for hypereutectics,they have a different material and run tighter clearences so when they expand they can butt the rings if their not gapped to the mfgrs specs.They dont come with rings but you can use pre gapped rings and just file them slightly to specs and it saves alot of money and work.
