Sanderson Headers C56AP-P Small Block Chevy Full Length

Sanderson Headers C56AP-P Header Set, Small Block Chevy, 1955–57 Cars

The C56AP header set is a full-length, 1-3/4″ primary tube design for performance SBC engines in 1955–57 Chevrolet cars. It fits a wide range of heads—straight plug, angle plug, and D-port—providing excellent ground clearance and compatibility with both automatic and manual transmissions (including Z-bar linkages).

The C56AP also clears both standard and GM 605 power steering gearboxes and fits select BluePrint engines. Not compatible with Brodix Speed Ports due to their unique plug angle.
