Jordan - heat, heat, heat and more heat to loosen that screw. I just went through the same thing with my new 500 project. Ultimately had to drill out the screw. Fortunately, the whole screw dislodged with the threads in tact after I worked on it for quite a while. Do yourself a favor, use SS and anti-seize when putting them back in. You may never have to open them again, but some poor sap many years from now might (who knows, may be you and your son in 25 years working on this bike. Especially now that you're getting wed!)
You can also use this bike build as a cover story about how you and said offspring will build lifelong memories in the years to come... Works on my wife, should work on yours too.
