Disconnect the exhaust manifold from the hcad. It isnot necessary to remove the exhaust do\vn pipe I'romthe manifold.9. Loosen all drive belts.10. On the right side, remo\.c the A/C compressormounting bracket and battei-y negative cable from thecylinder head.11. On the right side. disconnect the alternator supportbrace from the cylinder head.12. On the left side, disconnect the ail pump and powersteering mount bracket from the cylinder head.13. Remove the cylinder head retaining bolts.14. Remove the cylinder head and gasket.Thoroughly clean the gasket surfaccs of the cylinder headand block to remove all foreign material and gasket cement.Remove carbon deposits from the combustion chambersand the top of each piston.Use a straightedge and feeler gauge to determine thetlatncss of the cylinder head and block mating surfaces.Refer to 360 AMC V-K Engine Specifications, 'EngineAssembly' section of this chapter, for the proper tolerances.If the cylinder hcad is to be replaced and the original valvesreused. remove the valves and measure the stem diameters.Service replacement heads have standard-size valve guidebores. If valves with oversire stems from the original headarc: to be installed in a replacement head, ream the valveguide bores to the appropriate oversize diameter.If the original valvcs are used, remove all carbon depositsan'd rcface the valves. Install the valves in the cylinder headus] ng rcplacement valve stem oil deflectors. If valves withoversiie stems are used, oversize deflectors are alsorequircd. Transfer all the components from the originalhe,d chat are not included with the replacement head.Wire brush the threads of the cylinder head bolts prior toinstallation. Unclean threads will affect the tightening torque.Blow coolant from the bolt holes to prevent trapping coolant.InstallationI.2.3.4.5.Apply an even coat of non-hardening sealingcompound to both sides of the replacement headgasket.Caution: DO NOT apply sealing compound to thehead and block surfaces. DO NOT allow sealer to enterthe cylinder bores.Position the gasket tlush on the block with the stampedword TOP facing up.Install the cylinder head over the zasket.Tighten the cylinder head bolts evenly with 108 Nom(80 ft-lbs) torque following the tightening sequence(Figure 7- 19). Then repeat the sequence and tighten thebolts to I40 Nom ( I IO ft-lbs) torque.Note: The 360 AMC V-8 engine uses an aluminumcoated, laminated steel and asbestos gasket. Retighteninghead bolts after the engine has been run isnot necessary.On the left side, connect the air pump mountingbracket and power steering pump (if removed) to thecylinder head.. ..- -7'1
