Cylinder heads are typically checked for warping using a straightedge and feeler gauges. A straightedge is placed across the surface of the cylinder head, and any gaps between the straightedge and the head can be measured with feeler gauges. If the gap exceeds the manufacturer's specified tolerance, the head is considered warped and may require machining or replacement. Additionally, some shops may use a dial indicator for a more precise measurement of surface flatness.
To remove the cylinder heads from a 2002 Isuzu Rodeo, first disconnect the battery and drain the engine coolant. Next, remove the intake and exhaust manifolds, along with any accessories obstructing access to the cylinder heads, such as the timing belt or chain. Unbolt the cylinder head bolts in the correct sequence to avoid warping, and carefully lift the cylinder heads off the engine block. Be sure to clean the surfaces before installing new gaskets or components.
No, not necessarily. They should however be checked with a straight edge and feeler gauges for warping. If found to be warped then yes they may need to be resurfaced (at a competent machine shop)

When removing cylinder heads, the fasteners should be removed in a specific sequence to avoid warping the head. Typically, this involves loosening the bolts in a crisscross pattern, starting from the center and working outward. This helps evenly distribute the stress across the head as the bolts are loosened. Always consult the specific vehicle's service manual for the correct order and specifications.
To repair the heads on a 1987 VW Vanagon, first, remove the engine from the vehicle, then detach the cylinder heads by unbolting them from the engine block. Inspect the heads for cracks or warping, and if necessary, have them machined at a machine shop for flatness. Replace the head gasket, reassemble the heads onto the engine, and ensure all bolts are torqued to the manufacturer's specifications before reinstalling the engine in the Vanagon. Always consult a repair manual for specific torque settings and procedures.
