If the vehicle is fitted with a Rocam engine, the valve clearance is not adjustable, hydraulic lifters.
The camshaft caps are torqued in two stages, first 10Nm and than 90 degrees
for cylinder head the torque is : step 1 55 ft-lb, step 2 65 ft-lb, step 3 85 ft-lb. Rocker arm stud nut or bolt is 17 to 23 ft-lb. and valve cover bolt 72 to 108 in-lb.

Here is a suggested updated torque spec for this engine's rocker arm bolts;
Rocker arms
Step one: Torque to 11 ft lbs then tighten an additional 90 degrees of bolt head rotation. Some guys don't fuss with the torque specs and just get them good and tight. Either way, be careful, as the heads are aluminum. You do not want to over tighten these bolts
Could it be a F-150 instead?

These specs are for stock-type bolts with light engine oil applied to the threads and the underside of the bolt head. Moly and other lubes offer reduced friction and increased bolt tension, which will affect the torque figure. If you use after-market performance bolts like ARP's, you should follow the recommended torque specifications.
