Would be a good idea to check the gap from rockers to valves too.

Does she smoke while running?
Blue smoke?

If it missed a few oil changes the rings may be sticking in the pistons.
I have a product that will help with this.

Compressed air is real handy. Good point. My compression gage has a quick-release that fits an air line, but not all of them do. It will help isolate the problem area; listen where the air is leaking.
