Cadillac Repair: head gaskets, head gaskets, head gasket

Question
what would you say is the hardest thing about replaceing a head gasket, on a 1997 4.6 liter nourthstar?

Answer
Hi Jeff, Probably getting the engine out of the car to work on it. Otherwise it is getting all the special tools required to get the engine apart. And if you don't have a holder to keep the crankshaft from turning because you don't have the pliers that hold the timing chains in place it makes it tough to torque the harmonic balancer bolt. The whole job is kind of a charactor builder even though you may be a tech for 10 or more years. Bill
