There are a number of ways to set valves as you are seeing. Your post sounds like you might be trying to do it by the Rule of Nine's method, but your numbers don't add up. If, you haven't succeeded yet and haven't decided whose method to use, I suggest you go with Dieseltech's method for now.
Forget about the mag. Forget about feeling for compression. Always rotate the engine in the direction it rotates when running while making adjustments, to keep geartrain slack in the proper place. If you go past the point wanted you can back up, but back up more than need then turn forward in the proper direction to get to the point you need.
You have the rocker cover off, so look at the rockers. If #1 cylinder is at TDC on compression, both valves on #1 cylinder should be closed and the #4 valves "on the rock" (look closely at the rockers as you turn the engine and you will see the exhaust is finishing closing and the intake is just starting to open). The timing mark should be lined up, if you want to check it. Set both valves on #1 cylinder. Turn the engine 1/2 a rotation. Valves on number 3 cylinder should be "on the rock" and the valves on #2 cylinder will be closed. Set both valves on #2. Half a turn more and #1 will be "on the rock" so you can set #4's valves and half a turn after that #2 will be "on the rock" so you can set #3's valves.

Today's Featured Article - Grain Threshing in the Early 40's - by Pat Browning. The setting is rural Wisconsin, halfway between East Troy and Elkhorn, on Hodunk Road, our nation was at war, and I was 6, 7 and 8 years old. George was our "threshing neighbor." He was the one with the threshing machine, a JI Case on steel wheels, and he pulled it to our farm with a JI Case standard tractor also on steel. In those days, steel wheeled implements were common. The roads were general gravel, so the lugs cutting into them wasn't a problem. George would set up the thresher, s
