Pontiac Grand Prix Torque Specs Q. I have a problem with my with my car it is a 1989 Pontiac Grand Prix and I had to replace the head gasket and I was wondering what the torque number where for the head, and the lower and upper intake torque number. How would I clean the carbon out of the upper and lower intake by myself???? Thank you, Cory

A. As for the torque specs, I don't have a manual in front of me but they can be found on this web site and at most public libraries. As for the carbon in the plenum, I wouldn't worry about it. You could buy a couple of cans of carburetor cleaner and spray it inside intake.
