Thats a sign of detonation. Check your total ignition advance and your fuel 
pressures. Normally, a plug gap will either fire, or not, so thats not the 
cause of your detonation. The piston crowns likely look shot-blasted but 
unless they made really deep pits, the pistons will be OK. Any extra pieces of 
ceramic are long gone out the tailpipe. A fiber optic borescope can look 
thru the plug hole and inspect the piston tops without pulling the heads. My 
best guess- J Deryke
