What is a stopper head gasket?

A stopper head gasket has a reinforced bead around the combustion chamber. This design helps to contain cylinder pressure and prevent the gasket from blowing out, especially in high-performance or modified engines.

Will this gasket change my compression ratio?

This is a 1mm thick gasket, which is a standard replacement size. It's designed to maintain a 9.1:1 compression ratio for the 4B11T engine, making it suitable for many rebuilds without significant alteration.

What is the bore size for this gasket?

This HKS head gasket is designed for engines with an 87.5mm bore. It's important to ensure this matches your engine's bore size for a proper fit and seal.
