What is an incorrect result of resurfacing a cylinder block?

When resurfacing a cylinder block, the primary goal is to create a flat, smooth surface that will ensure proper sealing of the cylinder head gasket. However, it can lead to several outcomes, one of which is not applicable to the process, making it the incorrect result.

Resurfacing the cylinder block can indeed affect the overall geometries of the engine. For instance, it can change the clearance between the valve train components, such as in pushrod engines, resulting in altered valve train geometry. This reflects that modifications in the height of the cylinder block can influence the relationship between the pushrods and the rocker arms, potentially requiring adjustments to maintain the correct valve operation.

Additionally, resurfacing may also affect the alignment of cylinder banks in multi-cylinder engines, especially those using a V-configuration. Changes in surface height could lead to misalignment issues that could impact engine performance.

However, camshaft timing on overhead camshaft engines is typically not affected by resurfacing the cylinder block unless the alteration in height is significant enough to warrant timing adjustments. Resurfacing does not inherently change the timing of the camshaft unless it adversely impacts other components that control timing settings.

On the other hand, the compression ratio, which is determined by the volume of the
