You need an aftermarket serviice manual from Haynes or Chilton. They will have that kind of info.
I know of no car (I don't know them all) where that is needed and depending on the cover material (sheet steel or cast), could lead to warping and new leaks. I always use a thin film of silicone whether it is specified or not and there are torque specs for ALL valve covers I have ever seen.

This engine utilizes shims to set proper clearances, you will need a micrometer, valve clearance adjustment tool set for shimmed lifters,small magnetic arm, appropriate shim selecting charts (manufacturer will have this if you can get the nec. measurements).
Measure thickness of shims removed (using micrometer) and use this formula where T=Thickness of old shim; A=Valve clearance measured; N=Thickness of new shim required.
Intake valves:   N = T + (A - 0.02 mm (0.008 in.)) Exh. valves:     N = T + (A - 0.25 mm (0.010 in.))
Then you need to find shims as close as possible to the calculated values.
Valve clearances (cold) are as follows: Intake 0.15 - 0.25 mm (0.006 - 0.010 in.) Exhaust 0.20 - 0.30 mm (0.008 - 0.012 in.)
Note, if you are not familiar with precision measuring using a micrometer, this may be better left to a trained tech. These are high revving little power plants and you don't want a problem at 8K rpm.

You'll have to remove the engine cover under the bottom so you can position the new belt on the pulleys properly. Get a wrench or tensioner tool and turn the tensioner clockwise to relax the drive belt. Don't apply excessive force.

It's hard to draw a picture with words, but looking at the engine from the passenger side of the car, there are basically two top pulleys, two middle, and two bottom. The drive belt goes around the outside of the two top and two bottom, and on the inside of the two middle.
