1. Inspect the cylinder head for flatness using a straightedge and a feeler gauge. If tolerances exceed 0.0508 mm (0.002 in.) replace the cylinder head.
2. Inspect the valve seats for damage. Service the valve seats as necessary.
3. Inspect the valve guides for wear, cracks or looseness. If any of these conditions exist, replace the cylinder head.
4. Inspect push rods. Replace worn or bent push rods.
