Guys in the future, there are a couple of choices for removing the studs. They make a socket that pinches the top of the stud and removes it. You can also get the bottom ones with this socket. Snap-on and Matco sell them. If you can't get the stud remover from them, you can lift the head in the car, put a 2X4 between the head and block. Get a new pair of vise grips and remove them that way. It's not pretty but works. Make sure they don't slip on the stud. If you are worried about damage to the studs, get new studs from ARP. The new ones on some applications have allen head tops for installing. I have done this twice with the motor in the car. I thought that the head gaskets where on wrong and wanted to check them.
They where right. Rick L.
