Chevy Small Block Gold Zinc Steel 12-Point Head Intake Manifold Bolt Kit with Wrench
This TSP Chevy Small Block Gold Zinc Steel 12-Point Head Intake Manifold Bolt Kit includes twelve 3/8"-16 12-point head bolts with a 1" thread length, matching washers, and a wrench sized for the 12-point head, sized to install an intake manifold on the Chevrolet small block V8 family. The 1" thread length is built to support proper clamp load across the intake flange without bottoming out in compatible cylinder heads.
This kit fits the Chevrolet Small Block V8 Gen. I across its full displacement range — 262, 265, 267, 283, 302, 305, 307, 327, 350, and 400 CID — as well as the LT-based Gen. II in 265 and 350 CID, and the GM 90° V6 in 200, 229, and 262 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 gold zinc bolt set — with the matching wrench on hand — is needed for intake installation.
Fastener Specs
Twelve 3/8"-16 gold zinc steel 12-point head bolts, 1" thread length, washers and a matching wrench included.
Installation
Verify head style, torque sequence, gasket thickness, and manifold flange depth before final assembly to confirm the 1" thread length is correct for your combination without bottoming out in the head. The included wrench is sized to the 12-point bolt heads for installation.
