...Is there a good online article on adjusting valves on a inline 6?...
There are a number of different methods, most of them work well.
My preferred method is:
Drive several miles to throughly warm engine.
Remove valve cover.
Grab fan to turn engine over, sometimes pushing on slack side of belt to keep from slipping (engine not running)
While turning engine watch for a pair of valves (one cylinders worth) to close the exhaust and open the intake, this happens quickly with not much movement of the crank.
stop when the above exhaust valve fully closes and the intake just begins to open.
Now, in this case say that was the #1 cylinder that the valves just moved on, adjust both valves (to the warm settings by the book) on the #6 cylinder. This works because the #6 is very close to TDC and the valves are fully closed.
Repeat above until all have been adjusted.
The pairs of cylinders that can be adjusted are 1-6, 2-5, and 3-4, each when the matching cylinder just does the valve changeover the other cylinder's valves can be adjusted.
If working on any other even cylindered engine the same method can be used. Simply write the firing order, in this case 1-5-3-6-2-4, in two columns top to bottom then second half beside it, like
1-6
5-2
3-4
Now you have your pairs of cylinders to watch valves on one and adjust them on the other.
