If it has adjustable rocker arms one could be loose or you could have a bad lifter take the rocker cover off and start the engine and check where the noise is coming from

Test oil pressure with a gauge. Is the 'ticking' more noticable after engine reaches operating temp.? What SPECIFIC conditions make it better or worse? How many miles on engine?
