Neither. It seems like you're trying to do this without a service manual. They are for sale on this site.

This is starting to scare me a little bit. First of all I am going to attempt to make this very basic. If you have number one cylinder at top dead center on the Compression stoke, place a reference mark on the crank pulley. Also you can now set the valves on number one cylinder. The end one (closest to the front of the engine) is the exhaust. Use a piece of chalk or some kind of marker. Turn the engine 120 degrees in the direction of rotation (clockwise when view from the front) and set number valves on number 5 cylinder. Then turn another 120 degrees and set number 3. Then when you turn the next 120 degrees you should be back to the first mark and you set the valves on number 6 cylinder. Then the next 120 will be number 2 and then the last 120 degrees will be number four. The key is to get number one on TDC compression stroke. Remember cylinder travel in pairs so number 6 will also be at TDC, BUT NOT on the compression stoke. You can set all the valves on a 4 cycle engine in two full turns of the crankshaft.Questions?
