Best thing to have on hand is a maintenance manual to direct you through the process. There are digital copies all over the net for you to download as well. It's about 10 megs. If you can't find it I can send it to you if you like.

unscrew the 2 round covers from the left side crank case.
use a socket to spin the crank counter clockwise until you line up the straight timing mark with the mark on the case.
Put the cam gear in the chain lining up the 2 dots with the top of the head. There should also be 1 dot that is straight up.
Drop the cam into place with all the lobes going down.
Bolt the gear to the cam.
Double check to make sure everything lines up as described.
Bolt the valve cover on BEFORE you bolt the cam chain adjuster back into place.

And remember to decompress the cam chain tensioner BEFORE you install it back into the bike.

Pay particular attention on the install of the decompression pin....AND if it works correct with no binding. There have been rare occasions of the hot cams not having enough clearance for proper operation of the decompression mechanism. This happenned to me once before. Not trying to steer you away from the hot cams, just giving you a heads up. I have a stage 2 installed now and it works great. Timing chains are about $20, would'nt hurt to change it while your dad is in there.
In adding to maddog's response, definately make sure to install the collapsed tensioner BEFORE installing the spring and nut. If the spring is installed onto the tensioner and then installed on the engine, the tensioner is at that point fully compressed and you will run into major problems. Lots of people were running into this problem before and I am sure a lot of newbees are still doing this. If you need any advise, feel free to post or PM.
