Working great so far. They sealed up to the cylinders real quick and don't have any indication of excessive blow-by. 2 thumbs up.

So when running 10 -15 psi on a 402 can I just buy this set ( R-19112 ) and call it good or should I miss match ring brands, or is there a better way to go now on rings??????

Just to bring back an old thread because it comes up in searches, I don't think enough was said about how hard Hellfire rings are on factory blocks on an engine that will see a good bit of street miles. If you're okay tearing down your motor more often and are going to be in scenarios where you're constantly beating the **** out of it, they make sense. But if not, you're probably better off with high quality moly rings.

I've heard from the ring manufacturers that stainless steel rings are easier on cylinder walls than Hellfire rings, but you stated the opposite. Has anyone also heard that stainless was harsher than Hellfires?
