may be your rockers , did you inspect the ball rocker cups .
also you sure that its inside motor .
i have had noises that sound like ticking only to be exhaust leak .
leaking out bolt hole on my wrecker .
have a belt slapping also making ticking noise on a 350 in another truck .
your rockers not hitting valve cover ?

how old the timing chain ?
are you running the stock fuel pump ? can you un-bolt it and give a listen ?
the rod to it , maybe sticking or bent causing it to have lash making ticking noise .
hook up a lawn mower fuel tank and hang from hood to run long enough to try .
swap rocker arms if you have some extra's , are they riding all dead center on top of valves ?
i pulled hair for days to find out my exhaust was my problem on my 73 chevy wrecker , stock manifold leaking out bolt hole .
have lots to tell me i need to adjust valves ,till i show them the leak .
