04 mach tick, but different then head tick? Maybe?

[joeyg329]

Hey guys, my 04 mach has a very slight tick noise on driver side ( i searched and read though everything head tick related). It almost sounds like a leaky exhaust, only does it at idle, its maybe only louder then injectors but i hear it when im parked next to something or idling at the bank. car has 26k on it, and its a late model production car, 03 of 2004, shouldnt this have the revised head? I know most guys here said its louder with RPMs, mine goes away over 1100 or so, but at idle its annoying. Do i have the old tick? or could this be something stupid, like a pcv valve or a tiny manifold leak?

Second Note: I looked at the car and there is a sticker on driver side head that has a date of 08/17/2004?! I assume this head has been serviced or replaced?

Thanks and sorry for another annoying tick post
