the valve cover gasket is just a few bolts
as for the head gasket, you're required to remove the following
-valve cover
-timing belt cover
-timing belt
-remove head studs
-machine the mating surfaces
-new head gasket
-new head studs
and since you have the timing belt off
-new timing belt
-new water pump
-new water pump gasket
-torque everything to specs
-line up TDC on cams and pistons
-check with timing light
im sure i missed a few steps
