Nothing I'd call difficult...just tedious and a pain in the ass
A GREAT how-to:

Even though the how-to is for dohc, the procedure is basically the same. I can pop open the helms and get exact torque specs for you too (they're probably the same...but play it safe right?)
You can definately fix it w/ the tools you have. I would suggest that you replace the studs too though.
