03/05/01 MGA CYLINDER HEADS
We will try and provide you with information on the OEM style cylinder heads fitted to the MGA 1500 1600 and 1622cc engine blocks.
OEM STYLE REPLACEMENT ALUMINUM CYLINDER HEADS
These cylinder heads (smog or non-smog) are a direct replacement for the OEM style and also fit the MGB, however, when installing this cylinder head to your existing cylinder block the later MGB cylinder head gasket part GEG377 should be used. Do not use the original style gasket. Using this gasket will result in the gasket bore periphery-sealing edge intruding well into the combustion chamber area, resulting in head gasket failure.
