340 Piston to valve clearance w/RHS heads
You could detonate the Hypers pretty darn hard and they will never come apart like the picture you posted. Drop a Valve & Yes it will look like that along with taking out cylinder walls and putting holes in the side of the block! Guess How I know that....haaaaa
If you detonate with a Hyper piston Naturally aspirated the most I see it doing is busting a ring land and if that happens someone did a seriously bad job on the tune. I say run the Hypers, tune correctly and it will be just fine! It will last for years with them no problem!
