If the header bolts have vibrated loose it may have burned through the exhaust gasket a little to contribute to the noise.

And you may be due for a valve adjustment, if the exhaust valve has closed up tighter than .004 inch it would sound different, and be harder to start when cold.

Also a tight exhaust valve will burn over time.
