Ford Small Block Gold Zinc Steel Allen Head Intake Manifold Bolt Kit

• Set of 12 gold zinc steel Allen head bolts for a complete Ford SBF intake install.

• Includes washers; 2" thread length supports proper clamp load across the flange.

• Fits Ford Windsor small block V8, 260-351W CID, 5/16"-18 thread.

• Allen head design allows socket-wrench access in tight engine bays.

This TSP Ford Small Block Gold Zinc Steel Allen Head Intake Manifold Bolt Kit includes twelve 5/16"-18 Allen 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 Allen head gold zinc bolt set is needed for intake installation.

Fastener Specs
Twelve 5/16"-18 gold zinc steel Allen head bolts, 2" thread length, washers included.

Installation
Verify head style, torque sequence, gasket thickness, and manifold flange depth before final assembly to confirm the 2" thread length is correct for your combination without bottoming out in the head.

What size are these bolts?
This kit includes twelve Allen (socket-head) 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 Allen head bolts instead of hex or 12-point?
Allen (socket-head) bolts are tightened with a hex key or socket-driver bit, providing excellent tool engagement and making installation easier in engine compartments where there is limited wrench swing or clearance around the intake manifold.

What's the difference between this kit and the chrome hex or 12-point versions?
All three kits use the same 5/16"-18 thread, 2-inch bolt length, and fit the same Ford Windsor engine applications. The differences are the bolt head style and finish. This kit features Allen (socket-head) bolts with a gold zinc finish, while the other kits use either traditional hex-head or 12-point bolts with a chrome-plated finish.

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

Is gold zinc more corrosion-resistant than chrome?
Gold zinc plating is commonly used to provide excellent corrosion protection for steel fasteners. While both finishes help resist corrosion, the manufacturer does not specify a performance comparison between the gold zinc and chrome finishes, so no direct durability advantage should be assumed.
