Give your 351-powered Fox Body the headers to match
For a Fox Body with a 9.5-deck 351 small-block Ford, these Kooks headers include the adapter-plate arrangement for the stock-port-height heads. The 1-7/8" primaries lead into 3-1/2" outlets, giving your engine conversion a dedicated long tube exhaust component.
SKU: 10212450
Match the cylinder heads and chassis parts
The adapter plates provide the 2" inline stock bolt pattern for the listed head families. The installation requires a UPR or BMR Standard Series tubular K-member, Powermaster 9503 starter and Flaming River steering shaft.
Plan the engine position and ground clearance
A Stifflers transmission crossmember is recommended. Lowering mounts and engine position affect fitment and ground clearance; mount shims may be required. Gaskets and the bolt kit are included, while additional conversion parts can be needed.
Tuning for your exhaust upgrade
We recommend tuning with every header installation so the calibration suits your new headers, complete exhaust and fuel. Talk to us to discuss the right tuning route for your vehicle.
