Replace the gaskets?
I'd get all new gaskets if it were me if you have the cash.
But yes you can reuse your valve cover gaskets and intake gaskets, depending on your head gasket if its the metal type you can reuse that also but I'd get all new ones for shure for the rest dont forget your coolant crossover ones too they can be reused but for a cupple bucks why not.
But if money is a little tight you dont have to get your valve cover gaskets and intake gaskets that like 40 bucks or more right their and those are easy to get at if you have to replace them later.
