The C56 header is full length, 1 " primary tube header for performance engines in 1955-57 Chevy applications, and provides good ground clearance. The C56 clears both manual and the GM 605 power steering gears. Will work with automatic or manual transmissions (if using a hydraulic clutch setup - the driver's side header collector covers the holes for the mechanical clutch pivot). Will fit straight plug, angle plug, and D-Port cylinder heads. Works with GM HO and ZZ4 crate engines. Can be ordered to fit any GM or aftermarket cylinder heads (except Brodix Speed Ports). Comes with all hardware necessary for installation. Features a 16-gauge primary and collector tube thickness with a 3/8" thick flange and a patented flange design requires NO gaskets. Tightest fitting header available anywhere! Made in the USA. Includes the header bolt set and angle collector reducers. Our Aluminized Ceramic Coating is available and RECOMMENDED on all Sanderson Headers. We apply a multi-layer inside and outside silver ceramic coating in-house to meet our high standards of quality, and polish the coated header to a high luster. This coating provides aerospace and military technology to your vehicle to control the heat in your engine bay, improve cylinder scavenging of exhaust gases, and increase the longevity of your header investment. Copper Collector Gaskets are recommended for all Sanderson headers. Sanderson Headers do not include collector bolts due to our customers' wide range of preference. We do offer a collector bolt set that features Grade 8 Bolts with Locking Nuts. The Patented Leak-Free Design that Sanderson Headers offer you is the only leak-free flange design on the market ... Do Not Attempt To Use Flange Gaskets! The raised flange on the Sanderson Headers will buckle the gasket during tightening and actually cause a leak! Sanderson Headers are NOT emissions legal on pollution-controlled motor vehicles. It is the purchaser's responsibility to verify local regulations for compliance. Wrapping your Sanderson Headers with ANY thermal tape voids your header warranty. The best thermal protection for your headers is our Aluminized Ceramic Coating that is available for every Sanderson Header. Limited 5-year warranty.
