Buy a gasket kit for the upper end. Remove the valve cover intake and exhaust manifolds. Remove the head bolts. Remove head and clean up block from old gasket material. Take the head to a machinist and make sure that it is not warped. If it is warped either replace the head with a new one or have it machined true. Install new gasket and get torque specs with new head bolts and follow torque sequence using the correct torque specs. Clean exhaust, intake and valve cover of old gaskets. install new gaskets and torque according to specifications.
