First off, the engine is a 360, x heads, air gap intake, holley sniper injection, cheap hedman headers, mild cam, stock rotating assembly.
I have been trying to determine the cause of this tick that I have been hearing when driving. The sound is present at idle, cruising and deceleration. It goes away when accelerating and when I go around a left hand turn/bend at speed and it is almost amplified going around a right hand turn. I was thinking there is an exhaust leak but the turning symptoms seem kind of odd to me?
The sound isn't very loud when looking in the engine bay, but the sound is louder around the header collector when you're under the driver side. I don't see or feel a leak at the header/pipe flange and it sounds like it is inside the pipe right at the collector. Has anyone experienced something like this before? Is it the cheap/poor designed headers causing this?
 
One trick is to have someone block the exhaust at idle with a rag while listening for a change in the sound. That told me that my exhaust leak was at the manifold.

Well first off Headman headers are not cheap, I have been running the same set for 16 years. As for your ticking noise it sounds like you do have a bad Header collector gasket. I had the same issue a couple of years ago and after checking everything out the last thing was changing the gasket. The gasket looked in good shape that is until I seperated the collector from the header then is when the inner part of the gasket was pretty much burnt up. Installed new gaskets and Cha Ching, no more ticking.. Good luck to you..
