How does it affect performance? In general, thinner head gaskets can be better at sealing and raise the compression ratio slightly. Thicker ones will lower compression ratios somewhat. Any major changes in the compression ratio should happen with the piston, not the gasket. A thicker gasket will reduce the compression ratio by a small fraction, probably only by. This is by far the easiest method of reducing compression but the risk is that you are more prone to head gasket failure and the gains in lower compression are minimal.
