LOUD ticking comming from my motor :(

[leathal injection]

My head gasket blew, i took the job on by my self to change my head gaskets.

when putting my 1.6 svo rockers back on, i notice one of the rockers still have alot of play in it, even though the bolt is tight! i thought maybe bent pushrod, so i swiched it over w/ rocker next door. STILL alittle play, not a crazy amout though, not enough play for the push rod to come out of the rocker socket or anything but loose enough that can wiggle it alittle.

so i kept if moving w/my repair putting the motor back together, when i started the car a heard a crazy amout of rakcet going on , but i waited for the lifters to fill w/oil and it quited down alot , but theres a crazy loud TICK ! im guessing it that rocker that had play... why would that rocker have play when the rocker bolt if tightend till i can screw it down anymore ? ? ? someone told me i messed up a camlobe, but i thing my push rod would of bent before that would happen... please help
