Headers - V8, STAINLESS STEEL (fits 289, 302 & 351w)
Our NEW STAINLESS STEEL Long Tube Headers are designed specifically for the 66-77 Classic Ford Bronco. Our long tube headers provide more power and better sound than shorty headers. These headers were designed for the Early Bronco and therefore provide excellent clearance. It is even possible to remove & replace the starter without removing our headers.
With 1 1/2", 16 gauge Primary Tubes and 2 1/2" Dome Style Collector Flanges and 3/8" Mounting Flanges, these headers are built for performance and longevity. The headers come complete with gaskets, collector flanges and bolts and are solid one-piece tubes, not 2 piece slide together tubes. Headers fit 289, 302 and 351 Windsor. New flange-style collectors, requires no gaskets! Included reducers neck down to 2" OD.
These headers will work with factory straight end spark plug boots, but we prefer to use 135║ boots with these headers for better clearance.
NOTE: HEADERS SHOULD NOT BE USED FOR NEW ENGINE BREAK-IN!!! While these headers are designed to eliminate as many clearance issues as possible, if you have a manual transmission, you will need to bend the clutch bell crank rod for clearance. For fuel-injected 5.0 engines, these headers will work with GT40 heads. They will NOT work with GT40P heads. Use of aftermarket heads may potentially cause clearance issues.
SECONDARY NOTE: Some 351W Bronco's with manual transmission might require slight bending of the clutch bell crank for proper clearance. DOES NOT FIT 351 CLEVELANDS!
When aluminum heads are used, we commonly run into clearance issues with the frame rails. IF THESE HEADERS ARE MODIFIED IN ANY SHAPE OR FORM (GRINDING, CUTTING, COATING, ETC.) THEY WILL BE DEEMED UN-RETURNABLE! AS ALWAYS, WE HIGHLY RECOMMEND TEST FITTING BEFORE DOING ANY OF THESE MODIFICATIONS.
WILL REQUIRE MODIFICATION IF USING AN AUTOMATIC OVERDRIVE TRANSMISSION. Will require bending and grinding.
Also note, due to the extreme heat that goes through the exhaust, the finish on these headers will likely SLIGHTLY discolor after the first few initial uses.
