What’s the purpose of an oversized head gasket?
An oversized head gasket can be used to correct issues with improper deck height or cylinder head warpage. If the engine block or cylinder head has been machined, or if the engine has overheated and caused warping, an oversized head gasket can help to restore proper compression and sealing between the cylinder head and engine block.
Another case is if you are building a high-performance engine. An oversized head gasket is used to increase the compression ratio in an engine by filling the gap between the cylinder head and the engine block.This is often done in high-performance engines where a higher compression ratio is desired for increased power output.
Is an oversized head gasket necessary?
No, an oversized head gasket is not necessary for most engines. In most engines, a properly sized standard head gasket will provide a proper seal between the cylinder head and engine block, and will not negatively affect performance or reliability.
Installing an oversized head gasket in an engine that does not require it can actually have negative effects on performance and reliability, so it is important to consult with a qualified mechanic or engine builder to determine if an oversized head gasket is needed for your engine.
