Drain the cooling system and remove the spark plugs. Remove the intake manifold. Remove the Exhaust Manifold. Remove the distributor, including the cap and wires. On carbureted models, remove the fuel pump. Remove the Timing Belt. Remove the camshaft cover. On 16-valve engines, also remove the camshaft and intake Rocker Arms.

Do not allow anything to fall into the engine. Clean and inspect all threaded fasteners and be sure the threaded holes in the block are clean and dry. Place a new gasket and the cylinder head in position. The cylinder head bolts should be tightened in several stages following the proper sequence to the torque. Reinstall the timing belt. Reinstall the remaining parts in the reverse order of removal. Be sure to refill the cooling system and check all fluid levels.
