Pistons with multi relief cuts ???

I think there was a thread sometime back about pistons with at least two different valve relief cuts in them, does anyone recall that ?

Does that cost the user anything with a different set of heads, or does it not matter all that much to the combustion process?

Theoretically it matters, and with the right equipment the effects could be measured, but from a practical real-world perspective you won't know the difference.
CarsByCarl offers them from Diamond for stock stroke with the Kaase valve pattern also cut into them. They will work but in an app such as I had wanted to do they need to be deburred because the extra sharp edges will promote detonation when pushing the limits of pump gas.
