Regarding the cylinder heads, this removal and installation technique focuses on leaving the camshaft(s) as it is and retaining the exhaust manifold(s). First of all, the intake manifold should be removed before taking off timing chains, sprockets and guides. Then we go under the front part of the car securely supporting it before unbolting exhaust pipes from exhaust manifolds. Any other things like coolant fittings, cables or brackets connected to a head must be detached after they are properly identified. The cylinder head bolts should be loosened in an opposite order to their tightening sequence so that warping or cracking will not develop. It is important that when lifting off the engine block, any external components should be taken away for complete cleansing and inspection; at this point also include any other attached parts such as hoses and wires. On reinstallation make sure that each surface between cylinder head and block is perfectly clean without carbon deposits old gasket remnants or oil traces which can influence gasket sealing action. To do this use a gasket scraper and wipe with lacquer thinner or acetone. Shop rags may have been stuffed into blocked cylinders in order to avoid falling debris while a vacuum cleaner may be used to remove anything that might go inside there during material pouring out. Moreover, surfaces where both block meets head must also be seen for checks about nicks as well as deep scratches needing filling up or even machining it if necessary. Also chase I through with tap and blow them out with air hose till dry.Cylinder head bolts could stretch; therefore if one side does not touch straight edge, replace it.All warped cylinder heads including those of head gasket as well as intake/exhaust manifolds will require confirmation from automotive machine shop.The lash adjusters, camshaft should then start putting back what was removed from the Head.Firstly new cylinder head gasket should carefully placed over dowel pins on block noting its orientation.Should now take it and carefully have the gasket in place without interfering with the dowels.When installing head bolts, clean engine oil should be applied to M10 bolt threads with chamfered side of washers facing bolt heads if used.M8 thread on sealant is to be applied on head bolts.Install the bolts in their original locations, finger-tighten and then using an angle meter measure torque plus degrees. Lastly install timing chain guides, timing chains and timing sprockets while refilling cooling system change oil filter and add oil before starting engine for leaks of oil or coolant.

Clean the block and head mating surfaces thoroughly, checking for nicks and scratches. Check for warpage using a straightedge and feeler gauge. Clean the injector nozzle seats and the block deck surface, ensuring it's within specified limits. Chase the threads in the head bolt holes with a tap and die, and measure the head bolt lengths. If the bolts are stretched beyond the allowable length, replace them.

Block cylinders should be stuffed with clean shop rags to prevent debris from falling in, with a vacuum cleaner used to remove any material that enters.

Install new cylinder head bolts and tighten them following the recommended sequence.

Position the new gaskets correctly on the dowels in the block. Carefully place the heads on the block without disturbing the gaskets. Coat the head bolt threads with engine oil and install the bolts in their original locations. Tighten the bolts following the recommended sequence and torque specifications.

When installing the cylinder head, ensure that the mating surfaces are clean and free of debris. Place the new gasket over the dowel pins and carefully position the cylinder head on the engine block.

Remove the intake manifold and the exhaust manifolds from the cylinder heads. Also, remove the steering pump mounting bolts and move the pump aside.

For installation, position the new head gasket over the dowels in the block, place the cylinder head over it without disturbing the gasket, and apply engine oil to the head bolt threads and underneath the bolt heads. Install the bolts in their original locations and tighten them following the recommended sequence to the specified torque.

Before removing the cylinder head, it's important to relieve the fuel system pressure, disconnect the battery, and drain the engine oil and coolant. Additionally, remove the drivebelt, idler pulleys, air filter housing, and intake manifolds.

The new cylinder head gasket should be positioned over dowel pins on the block, taking note of its orientation.

To complete the installation, components removed from the head, such as lash adjusters, exhaust manifold, and camshaft, should be reinstalled.

The initial steps are to relieve the fuel system pressure and disconnect the battery. Drain the cooling system and remove the drivebelt. Take out the PCV and EVAP system components, as well as the cowl.

Remove the banjo bolt, sealing washers, and the fuel line from the rear of the head, then remove the fuel injectors. Remove the rocker housing and gasket. Loosen the head bolts in the reverse order of the tightening sequence, inserting each removed bolt into a cardboard template to keep track. Carefully pry between the head and block to break the gasket seal, then lift off the cylinder head, either with an assistant or using an engine lifting hoist. Inspect the head and remove any wiring harnesses or ground cables still attached.

Depending on the cylinder head, you may need to remove other components like the alternator, transmission and oil dipstick tube, air conditioning compressor, or heater core tube. Additionally, the timing chain cover should be removed, and the crankshaft should be rotated to Top Dead Center (TDC).

On the catalog it doesn't say if it for oil or coolant. it just say plug.
