After resurfacing the cylinder head, check the flatness of the surface using a straight edge and a feeler gauge; replace the valve guide seals using a valve spring compressor to remove the valves and generously lubricate the new seals before inserting them; fit the thermostat and its connector; install the exhaust manifold with a new gasket; repeat the flatness check on the cylinder block; re-tap the threads of the cylinder head mounting holes, ensuring no debris falls into the cylinders; apply the new cylinder head gasket and the cylinder head itself; insert the new rocker arm pins, the new camshaft with the relevant oil seals, and finally seal the rocker cover with sealant.

Use a new stud kit to secure the cylinder head and align the timing marks to fit the timing belt.
