Which piston rings should I use?????

Hastings manufactures rings for Sealed Power, Speed Pro, etc, they do not make Mahle, Akerly & Childs, or Total Seal rings. The premium rings are much higher quality. You pay more for a reason. Similar to pistons. You pay for CP or J&E for higher precision and higher technology. The question is do you need a premium ring. I'd say no - but it's not a bad place to spend a little more because you will get dividends whether it be in more power, less oil contamination, or longer life.

The last set of childs & Albert rings I had were nothing more than badly made junk, to the point where I sent them back to the supplier at my cost and I'm in Australia. Got them to send me the tried and true Sealed power / speed pro / hastings? Problem solved.

So don't think that the more you pay the better the product.
