In most cases..no. Like Bill stated, you may have lost the bearing(s) from a rocker. If that's the case, replace the rocker, and drain the oil, because the bearings have probably traveled to the pan. You may find a cracked spring, which just requires replacement. If you find a bent pushrod, the head may have to come off, but a leak down test will tell you that.

ok i took the valve covers off (both sides) and everything is in place.... i even called a buddy of mine to give it a double check and he agreed that everything was good in the valvetrain
so i put the valve covers back.... and fire the car up after 2 weeks for my buddy to hear the noise... the car starts up and the noise is there off coarse.... but after 5-6 min of idling the noise is gone completely.......
weird, it sure sounded like some thing was loose in the valvetrain....and now its fine??
i recorded a video but i dont know how to post it... i can email it though
thnks guys

But how does the engine run under load? Have you taken it out on the street?
You may have a lifter that is starting to go south on you. If it collapsed earlier then you would have had the loss of power and valve train noise.
