Default Valve Cover Gasket Replacement

Hi All-
Went to change my sparks the other day one had a good amount of oil on it. I had been getting a check engine after a misfire and an engine lean warning. Also had to fill the oil early once... I am guessing I need a new valve cover gasket on the side that had oil in the spark tube and tube gaskets. I have all the parts and plan to go at it this weekend. Does anyone know if there are any diagrams out there and/or torque specifications for when I put the cover back on?
I plan to video it since I see no how to's anywhere. Any help would be great. Going to be working mainly on the passanger side, but replacing the sparks on the driver side too.

7 ft/lbs for the small bolts (includes the bolts with the seal washer)
15 ft/lbs for the large bolts

Thank you very much! By any chance do you know the tightening sequence for the valve cover on the passenger side?

From what I recall there is no tightening sequence in the service manual. I would probably start from the middle bolts then go in a criss-cross or spiral pattern.

^I agree. Start in the middle and work outward; probably a similar sequence as one would do head bolts/head studs.
