Well I got the head off the car and the gasket had failed in 2 places. I took the head to a motorsports shop in Valencia for re-work. The shop called with an issue with machining the head surface. Apparently the head was not warped, but 2 small "channels" had formed between cy 2-3 and between cy 2 and a water jacket. They had those areas built up with weld and then machined the surface down. Total amount removed from my head surface was only 0.005".



Other than that the valves, guides, springs, etc was in excellent shape. The cylinder walls looked very nice as well. The car has 115K miles on it.

Did you actually have a head gasket failure as your reason for removing? Reason I ask, I rebuilt a highmileage 944 motor that was running fine with 187k on it and the gasket was nearly see through!



Good luck on your top-end and let us know how it goes...

yes, that was what I suspected. I was losing water, slowly, and it had turned blackish in color. The real issue was the grooves that was allowing water to leak.
