Replacing my valve cover gasket.What else should I repair/inspect while I'm in there?
 

hey hey,
So I'm going to replace my valve cover gaskets and i wanted to know what else I should consider replacing and/or checking while I'm in there.

My Z's been been sitting for about a year and a half.
So I know there's gotta be tons of stuff I should be checking and fixing.

All suggestions would be super fantastical.
Even the smallest detail.
I want my Z running right. ^__^
