Erik Always brings to the forefront An idea or technological quizzery that I dearly miss. Thanks Erik, I was wondering where you were Good point bud, let's find out whether these are coated or ductile sets of rings as for sake of discussion. Also, who set the clearances and double checked the performance under run conditions. One thing that is a constant; HEAT. It has to build the tempermant for life of the engine during it's cycle for life. chrome, "moly's", cast which ever you have set the system up for will need the heat to set. Thanks for bringing the reminder of the construction of the rings forth and what material they could be laced with, they are much better than they ever have been for the longevity purpose of our builds. I appreciate your endevors with your posts Erik.

About twenty years ago if one of the dirt burner cars hit 250 F to many times you would loose your ring seal.
First it would only be a 10 lbs. differance between each hole then it would creep up to 15 lbs. between each hole.
With today's better ring material you can hit 250 F and not loose ring seal or blow head gaskets.
I would rather keep the temp. at 200 F for max. HP/TQ and longevity but this is not always possible.
