Gasket and other parts needed for a cam install
 

I will be having my mechanic install a cam on my 94 993. Aside from the lower and upper valve cover gaskets, what other parts do I need? I want to order it here, in Pelican, but want a complete list so that the install goes smoothly.

Anybody want to share their knowledge on such a simple task? Should I just go for the overhauling head gasket kit? My mechanic says my parts will be there but I have no need for head gaskets. If I eventually get billet heads then I would need to get another head gasket kit since this one will be missing parts from this cam installation.
