Valve cover gasket question
 

Hey guys and gals, yet another age related issue showing up on my 02'.
My valve cover gasket is leaking, and while that doesn't seem to be a difficult task, I still have a couple questions.

1. To RVT or not to RVT, I've had good and bad luck in the past using it, just wondering what you think.
2. I have done many sb Chevy valve covers, but not one 4.0 cover. Anything I should watch for?

Thanks
