Compression Stroke after verifying TDC

I just hook up a compression tester to #1 cyl. Then you can turn crank w bar and check guage when get to your mark. I noticed that you have adjustable rockers. If you can rotate push rods then you don't have any preload. Is that what you want?

That's a good idea also. I'll have to get a set for the future. The valves were adjusted some time ago, but I am going to check them again.
