I didn't see my favorite method for setting valves, so I'll add it to the list.

- Roll engine until rocker arms for #4 cyl "rock" (exhaust valve closing and intake valve opening). This puts #4 at (or very near) TDC on the intake stroke, so #1 is also at TDC with both valves fully closed and ready to adjust.

- Roll engine until rocker arms for #2 rock, adjust valves on #3.

- Roll engine until rocker arms for #1 rock, adjust valves on #4.

- Roll engine until rocker arms for #3 rock, adjust valves on #2.

This method does not require you to look for timing marks, pull the dist cap, or anything else... you're simply using the relationship of the cylinders to each other, to determine absolutely when a pair of valves are closed. This is essentially 4 half-turns of the crankshaft start to finish, and is pretty much idiot proof. I should know. :-)
