G, the ticking you hear @ cold start is more likely being caused by a weak hydraulic lifter. A lifter may be bleeding down when the m/c is not running. The sound goes away when the motor rebuilds oil pressure in the lifter. If there was carbon build up on your valves, the ticking usually lingers even after the m/c is @ running temp.
