On this pass: YouTube - DougsfastZ 10.58 pass the fuel pressure regulator vacuum line came off and went lean, 13:1 AFR's. This was the outcome
#2 cylinder blew the RJC .019 stainless head gasket and melted the ringland
#3 piston has some detonation pitting but looks salvageable. Headgasket was stretched as well
Matching chamber
Block and other pistons look fine. I'll pull it down, check bearings, put in a new piston and get it back up and running.
