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.

If you have the 4afe engine, normally you need to check the idle control valve if it needs cleaning. Check also the timing of the car.

If you remove thermostat water will circulate too fast and will not cool down, replace thermostat and check if your fan is turning in correct direction. Also make sure your ignition timing is ok. I found on some vehicles the waterpump seems ok but when vehicle starts heating up the impeller gets loose on the shaft. Check your brakes if they are not binding.
