Unusually easy to lift #5 valves

This illustrates the issue I found after starting the engine. I noticed a "tinging" noice coming from the right side of the engine. After pulling off the valve covers to check the valve clearences I noticed that the #5 intake and exhaust valves were noticebly easier to despress. This shows me depressing the #5 exhaust valve with only the tip of my thumb.
