Your car has hydraulic lifters. These lifters can and will adjust be filling with engine oil once the vehicle is started. They take up the slack that is left in the push rod/rocker arm assemblies to prevent noise and allow the valves to open and close at the proper time.
Some engines will need to have the rocker arm and push rods adjusted such as the small block Chevy V-8's, some Fords, older OHV engines, etc.
However, most modern engines use the technique I sent you; meaning that they call for a torque specification and then turn the bolt an additional angle (90 degrees, 45 deg, Etc).
