Just check if the bolts are there. Mine had a leak and the ticking went away. It's hard to diagnose someones problem with out being there and hearing it. I just know the exhaust manifold thing was very common and gm never put up a tsb for it.

My 2006 Sierra 5.3 has the same issue. I noticed the exhaust manifold bolt at # 1 cyl. is missing the head. Just curious, did yours tick from initial start, or only when warm? Sorry,a little late to the party.
