This reminds me of when my friend was trying to remove the intake manifold from his IH Travelall....
It was stuck on there pretty good, so he just hooked up a chain around the coolant runner, and looped it over the fork lift we had there in the shop...
Lifted up the front of the Travel All, and then BANG! It snapped the intake manifold in half....
So, what's worse, we brazed the cast iron manifold back together, and then set it up on the mill in his dad's machine shop.. It was running really good along the cast iron, taking off just a skim of metal, and then it reached the much stronger brazed material... BANG@!
There goes a few hundred bucks worth of fly cutter... Dang! His dad was really pissed, but we did manage to get a smooth gasket surface with a grinder... LOL
Later he jumped that massive "Suburban" like vehicle about 50' across a field, and ripped the shocks right out of the frame mounts... Then we put the engine into the radiator crossing a stream.. (Who would have thought 4' deep water would cause a truck going 60mph to stop so quickly? LOL As if jumping the rig would not have done it.. but I think that might have contributed to the engine mounts being ripped loose, so they would allow the engine to fly forward and have the fan cut a neat circle into the radiator...)
OK, so if you have not put down the tools, and step away from the vehicle yet, please do so now. Trust me, you don't want to learn the hard way like my old buddy did.
That being said, easy out's are a great way to remove ARP studs. (They just dig into the allen keys on top, and remove the stud, where the allen has just stripped them. You might need a few gentle taps from a brass hammer to get the easy out into the stripped allen key, but pick one that's a tight fit, and tap it into the hole, then gently remove the stud.)
Good luck.
