The "best" would be fluorolastomer gaskets with little stops to keep you from overtightening them. I think felpro makes them. They are usually blue. Completely reusable. Expensive but worth it.
Look at your heads and see if the valve cover bolts are in a straight line from the exhaust side to the intake side, or if they are offset. Choose an appropriate gasket with that info.
Make sure the sealing surfaces on your valve covers are straight. You may have to hammer them a little. The stops in the new gaskets should keep them from getting bent again. You might need longer bolts. Good luck.
