A multi-layered gasket for a combustion engine having a plurality of active and spacer gasket layers that are removably secured together is disclosed. The active layers are arranged in face-to-face engagement with the spacer layers in an alternating manner. The spacer layers may be selectively removed or added to vary the compression ratio of the engine. Alternatively, spacer layers may be selectively substituted with additional spacer layers having differing thincknesses to selectively vary the compression ratio of the engine. Retaining mechanisms for removably securing the gasket layers together are also disclosed.
