New DB4GT Cylinder Heads
These heads were produced from original drawings and up rated and updated as necessary. All new computer generated drawings and tooling were used. These heads are cast in Los Angeles for us. There are improvements in gas flow as well as spark plug fittment. All the parts necessary to convert a standard DB4 engine to a DB4GT are available. From the air box to the exhaust manifolds from the head gasket up to the cam covers and the ignition wire looms. We make the cams, the distributor drive boxes and the gears. The gear boxes will accept the original tachometer drive boxes and the later style Smiths drive boxes.
