Description

This TSP Ford Small Block Chrome Steel 12-Point Head Intake Manifold Bolt Kit includes twelve 5/16"-18 12-point head bolts with a 2" thread length and matching washers, sized to install an intake manifold on the Ford small block Windsor V8 family. The 2" thread length is built to support proper clamp load across the intake flange without bottoming out in compatible cylinder heads.

This kit fits the Ford Small Block Windsor V8 in 260, 289, 302 (5.0L), and 351W CID. Before installing, verify head style, torque sequence, gasket thickness, and manifold flange depth against your specific engine combination.

Common uses include street performance builds, restoration projects, and custom engine assemblies where a complete, correctly sized 12-point chrome bolt set is needed for intake installation.

Q&A

What size are these bolts?
This kit includes twelve 12-point intake manifold bolts with matching washers. Each bolt features a 5/16"-18 thread and a 2-inch length.

Will this fit a 302 or 351W?
Yes. This bolt kit fits Ford Windsor small block V8 engines, including the 260, 289, 302 (5.0L), and 351 Windsor (351W).

Why use 12-point heads instead of standard hex?
Twelve-point bolt heads provide more socket engagement positions than standard hex heads, making them easier to install and remove in tight engine compartments. They are commonly used on performance engines where clearance around the intake manifold is limited.

Will this fit my Mustang, F-100, or Bronco?
Yes, provided the vehicle is equipped with a Ford Windsor small block V8 in one of the supported displacements: 260, 289, 302 (5.0L), or 351W.

Are washers included?
Yes. The kit includes all twelve intake manifold bolts along with matching washers.

Is this the same thread size as the Chevy small block bolt kit?
No. This kit uses 5/16"-18 threads, while Chevrolet small block intake manifold bolt kits use 3/8"-16 threads. The two bolt kits are not interchangeable.
