My last time at the track in the fall I got back to the pits after a pass and found the coolant overflow tank overflowing. No water in oil or oil in the water but I still figured that I had lifted a head and blown a head gasket.
Finally got around to changing them this weekend and both gaskets had failed. The were both bad on the middle cylinder with the blowout happening towards the exhaust port. Neither gasket was damaged nor was there any other damage but they were defiantely blown. (See Pictures)
Pistons looked perfect so I don't think there was any bad detonation damage to them but there was a gritty deposit on some of the intake valves making me think I should find some pitting somewhere on the pistons but I could not.
