Just finished the valve cover replacement in conjunction with the V2 pvc check valve kit. I wanted to post here that my valve cover was very stubborn to get off. I had to run a putty knife between the gasket and the head where ever I could get access. Even then, I had to grab the top of it on the intake side with some extra large channel locks and wrestle it back and fourth as I pulled up to get it to release. For such an accessible item, it was quite a PITA. Probably didn't help that I was tired from just finishing the intake.
