Leaky Valve Cover

Clean all the rtv off, that you used. VC & Cylinder head.
Glue a new VC gasket ( i like cork)to the VC, using Edelbrock Gasgacinch. Put Gasgacinch on both the VC and gasket. Let it set up, then install the gasket on the VC. Set the VC flat on a bench with some weight on top, and let dry over night. Now the gasket is glued to the VC.

Now apply a thin layer of grease to the other side of the gasket,and lay it on the head.
Use the factory bolts, that's all you will ever need.
Tighten them snug, do not over tighten them.
That's it.
