I have spares in my glove box. Probably don't live anywhere near you, however.
Some torque wrenches, such as the one I bought at Autozone, are very innacurate. I ended up stripping a valve adjust screw as well, and couldn't find a donor motor at the local bike boneyards, so I ended up going the bikebandit or whomever route. Since then, I've taken everyone's advice here about gutenteit (good and tight, don't sweat the torque), which has worked rather well for two subequent valve adjusts.
Also, several here have commented that you can often stretch the valve adjust interval once you have several tens of thousands of miles on your bike, as they often don't drift out of adjustment as quickly once you have a well broken in motor. If you pop the valve cover for you next valve adjust and find everything mostly in adjustment or just slightly off, that'll be a good indication that you may be able to stretch the next adjust. I'll leave this to the resident experts to comment on though.
For new owners, of course, you probably should pop the valve cover anyways as you won't truly know where things are gap wise until you look.
BTW, it has been recommended by quite a few Connie owners here to set your valves to the 'loose' end of the range, as the trend seems to be that they often tighten up between adjusts. Plus the wider gap helps tighten up the intake and exhaust intervals slightly, which bumps the low end engine torque a slight bit. Steve In Sunny Florida's extensive cam work has shown that, in stock form, the Connie's exhaust cam interval has a little room for improvement, especially at the low end.
I love the fact that with this bike doesn't use shims. I'm sure those aren't too bad to work with, but I like the adjustable nut and stud method better.
One other thing. I was having issues trying to match the nut with a new nut with proper threading. I don't think the valve adjust studs use either 'common' metric thread spacing, but as I ended up ordering extra 'factory' nuts and studs anyways, for me this shouldn't be a problem for a bit.
