SBC Water Header

The SBC Water Header from Dedenbear is a specialized cooling component designed for Small Block Chevy engines that have undergone performance modifications. This water header is ideal for those building street machines, drag racing platforms, or high-output cruise cars, providing a lightweight alternative to the factory cast-iron unit.

Constructed from aluminum, this water header assembly bolts directly to the cylinder head and directs coolant to the radiator with improved port geometry compared to OEM iron pieces. The internal passages are engineered to minimize dead spots and promote laminar flow, which helps maintain consistent cylinder head temperatures during high-RPM operation.

SBC enthusiasts utilizing carbureted or fuel-injected small-blocks will find significant benefits from this header, particularly when paired with upgraded radiators or electric water pumps. Its compact dimensions ensure compatibility with common intake manifolds and mechanical fuel pumps, making installation straightforward in modified engine bays.
