Stainless Steel Shorty Headers, w/ Mounting Hardware (fits 289, 302, 351W)

Bolt-on horsepower and torque with these short-tube headers. These headers are designed to fit 66-77 Broncos with 289/302/351W motors with ample clearance for most modified suspensions. They are engineered to make strong power and torque throughout the RPM range with smooth mandrel-bent 1-1/2 inch primaries and 2.5 inch collectors. Each header is manufactured with heavy-duty features like extra-thick 3/8 inch laser cut flanges to guard against warping and heavy-wall 16 ga tubing for maximum durability. Made from 304 Stainless Steel ensures these will last for many years to come. This header system includes high quality hardware, premium laminated metal core gaskets and heavy duty ball and socket flanges for a leak proof installation. Also includes ?O2 Ports in Collectors for EFI conversion.
NOTE: These headers are not ceramic coated. Stainless material will discolor during use due to the high heat of the exhaust system. DO NOT use headers to break in a new engine. Use of 13/16 inch spark plugs may require grinding of headers for socket clearance.
