The best tip i can give you is this. Make sure the valve covers and the cylinder head itself are very very cleans. Make sure the old gasket is completely removed from both before you attempt to reinstall the valve covers, or you will be doing this job again very soon.
I would use a good brand name gasket such as FelPro, no cheapo gasket. Should use a cork gasket with a small amount of rtv just to hold the gasket in place. Tighten the hold down bolts a little at a time, not all at once and dont over tighten them. They will break with heavy force and ooze out from underneath.
good luck

Either gasket material is fine.
You NEVER EVER use RTV on valve cover gaskets. Here is why.
RTV is not a glue it will allow the gasket to slip out of place by actually lubricating the gasket even after the RTV cures. When you use RTV on engines, you use it ALONE without a gasket or at gasket joints IN SMALL dollop AND.....you do not use bathtub type "smells like vinegar" caulk RTV. It won't hold up with the oil. Use a High-temp automotive grade that is marked as safe to use with oxygen sensors.

Rubber has a better Resistance to the constant changes in temperature. But whatever you do, don't use rtv. It's not needed and can cause damage if it over flows into the engine. Put all the screws into valve cover than place gasket on valve cover. then let it sit in the sun for a few minuets until it isn't curly anymore. than put on engine.

I prefer to use cork for a few reasons: A-It's easier to install, and B-It's easier to tell when the need replacing. THe seal better also. But please, for the love of god, do not forget your orange sealer, or you'll run into big trouble down the road. Otherwise, just take the covers off, remove excess sealent from the valve covers and cylynderheads, and the put the sealer on BOTH sides of the gasket, and replace the valve covers. It's that simple.

I would go with rubber if I could. Just a little bit of RTV sealant with cork to help hold the gasket in position, is normal.

when it comes to gaskets you get what you pay for. buy the best you can afford. valve covers tend to get removed and replaced a couple of time during valve adjustment, so only use sealant on one side I recommend applying the sealant to the cover itself and letting it become tacky or setting before installing the cover. if you use a good quality gasket and don't over tighten you should be able to remove them a couple of times before the gasket becomes to compressed to seal. once all adjustments are done follow mfg recomendations on tightening sequence and torque settings. valve covers are easy to bend and then they wont seal no matter how good a gasket or how much sealant you use.

rubber is better but only use silicone between the valve cover and the gasket. this way when and if u gotta take them off ,they come off easy and then u can put them right back on with no trouble
