Headers for Big Block Chevy
New from The original DOUG’S HEADERS, the D316 tuned long tube header, is engineered to fit 396-502 Big Block Chevrolet engines in very confining engine compartment environments and still give the maximum ground clearance possible. Designed specifically for 1970-72 Camaro, 1968-74 Chevelle and El Camino.
These headers are built with 3/8” thick flanges at the cylinder head and 3 bolt outlet flanges. The 4 tube under chassis exit design is made from 16 gauge tubing for durability with big 1 7/8” primaries and 3 1/2” collectors for increased horsepower and torque throughout the powerband. Designed to work with both automatic and manual transmission cars equipped with power brakes, power steering and air conditioning.
They come standard with a polished high luster heat and corrosion resistant metallic ceramic coating for a rich appearance and long life. These headers come complete with reducers, 1100º F rated gaskets and premium installation hardware and instructions. Headers are also available uncoated.
