Do you mean the head studs? If so, here's something I wrote to the CorvAircraft list a few weeks ago: I'm not sure why you'd want to remove those head studs, but conventional wisdom is don't even remove them at all! That's a critical joint that was supposedly created in the manufacturing process, and is difficult to reproduce if you back the stud out and then put it back in again. I did that with my first case, and then called Bob Sutcliffe to tell him I'd removed them for easier shipping. He basically told me I'd reduced it to junk, and he personally wouldn't bother putting it back together. Maybe you're thinking you need to replace them due to rusted threads or something...and if that's the case you may not have checked the price of replacement oversized studs. They are expensive enough that a full set would buy you another core engine with studs in better shape. Maybe I don't understand your problem, but what most people do to get the heads off is grab the stud with ViseGrips and loosen the nut, or simply split the nut with a chisel or grind a slot in it to cut it in half. I split just about every one of mine to make sure I didn't loosen that critical stud/case connection. ------------------------- Maybe you can get away with using something like Loctite 620 to put them back in, but in CorvAircraft circles, that case has now been compromised.
