Valve cover leak, Help!

Add another to the "had to grind them to clear the intake" list. Even then I couldn't get them to seal up with cork or standard rubber Fel-pro gaskets. I finally got them sealed up by siliconing cork gaskets to the covers then installing them. No silicone on the head side though. Had them on and off about 4 times now and they still seal fine. 95 inch lbs. isn't very much so watch using a 3/8 drive. Like 340sRule said a 1/4" ratchet is the best to use.
