you would be advised to get a spare lower chain cover gasket, they can split during removal. About £20 each.
I would advise to just buy just a head gasket unless you plan on stripping down the head. About £45 each.
There are few gaskets on a z22se engine, the sump and lower craddle use sealant (no gasket), then there is only the front and rear crank seals, head gasket, valve stem seals, inlet gasket set and cam cover gaskets (they are both rubber and can be reused) and lastly the metal exhaust gasket and egr gasket.
