Besides a torque wrench and a set of feeler gauges, it doesn't take anything special....and those aren't what I would consider specialty tools.
Just doing the clearance check itself is pretty simple. You may be one of the lucky ones who doesn't need to adjust the valves. I wouldn't bank on it that, though. Anyway, while you're to the point of doing the check you're already in there for the air filter and spark plugs.
My suggestion in a case like this is to bribe one of your friends who may have some more experience than you do. Buy good steaks and good drinks. Have them stand over your shoulder helping you, and they can jump in as needed. Heck, if your buddy lives across the country you could fly them out for the weekend cheaper than taking it in. I could be your buddy, I'm free most of the time and I love to travel, and I love good steaks and good drinks.
Here's my video, may be helpful or may not be. I did a bit of a "cheat" to make it easier but it's really not that much trouble to take all the stuff off the right side to get in there to see the timing marks. I did the manual cam chain tensioner during the first valve adjustment, zero regrets and never had to mess with it after initial setup.
