Ron, It's probably not an exhaust leak as it's loudest when the engine is cold. A noisy rocker on the other hand is loudest when the engine oil is hot. It could also be a worn cam lobe or a partially clogged rocker oiling passage.

I have a "tick" that you only hear under acceleration, doesnt change with engine temp, and is quiet at idle or cruising rpms. It also goes away as you approach the 4K rpm range during a hard acceleration. Im leaning towards a gasket leak... any thoughts... advice?
