Its a long process, as you have to pull the intake, and most of the front cover off the motor just to pull a gasket. The gasket kit sells for around $120 or so from Ford. You might find them elsewhere. 2 hours will not even get you through the tear down phase of the job. Then you must clean the heads themselves, and check them to make sure you don't have to resurface the heads. Then you can start to build back up and that will take longer then the tear down phase, I suspect. Also, you will more then likely be replacing more then just the headgaskets. The intake gaskets, exhaust header gaskets, and valve cover gaskets MUST be replaced as the items are pulled off to get to the heads.
Yes, I'm currently working on a head gasket problem on a 1996 Mustang V-6 that has 166K miles and I'm led to believe the origional factory head gaskets. However, with the gasket blowing and ending up with part of it in the cylinder chamber I've gouged the piston and I'm afraid to see how bad the rod may be bent under that. So, I'll be tearing the motor down to make sure my rods and my crank shaft are okay then bandaging this motor until I can do a V-8 DOHC swap.
Just some information I've found in the last couple of weeks during my mustangs woes.
As for twisting Fords arm? Good luck, its highly doubtful.
