Getting my ex cam and headstuds install this weekend, do i need to replace the head gasket as well?

 

are you removing the head? if no, then no need to replace the gasket.
if you do, you can still reuse the gasket since it metal. however, the gasket is only $35 from the dealer, so its cheap enough to replace. moreover, i would take the head to a machine shop and make sure the head is flat.
