The head gasket in my 98 GT is blown (compression was around 150 in every cylinder except 2 and 3 which has 120). I have a set of PI heads Ill install when I do this, but the motor has 175K miles. I'm considering pulling the motor to do the head swap, and if I do pull the motor, I'm considering rebuilding the bottom of the motor. Since it's a manual, I'll probably replace the clutch and get an aluminum flywheel. I'm also considering slapping headers on it since the motor will be out. Does it seem like I'm going overboard? Money is an issue, but I have another vehicle so this can sit while I acquire parts.
