Hello, I'm new to these forums and my friend recently picked up a 1999 Mustang GT that turned out to have a blown headgasket so we're tearing his engine down in his driveway (while in the car) and we got the heads off and everything looked really good except for cylinders 6 and 7 on the drivers side had some scoring (the head gasket blew in between the two cylinders pretty badly). The rest of the cylinders still have pretty healthy cross hatching...
