do a leak down or compression test across the cylinders to determine static combustion pressure across the cylinders. This will determine if one has internal issues.

A tick, tick, tick, check your exhaust manifold/down pipe for a hole/crack, a small leak in manifold/down pipe will "tick". 94

A diagnostic test where you pump air into a cylinder and measure how much of the air "leaks" out of the combustion chamber. Up to, say, 10% is acceptable.
This test is more useful than a simple compression test, because it can help you determine exactly where the lost compression is going...ie past rings, intake or exhaust valves. You simply listen at the intake manifold (in valves), exhaust pipe (ex valves), or dipstick (rings) for the sound of air escaping.
For my money, the best diagnostic tool you can use for top end problems.

don't remove the head yet, the leakdown test that 3 people already suggested will tell you if you have a bad valve, and then you can go from there
