Product Details

Features

  • Set of 12 gold zinc steel 12-point bolts for a complete SBC intake install.
  • Includes washers and a matching wrench — a complete, install-ready kit.
  • Fits Chevy SBC Gen I, Gen II LT-based, and GM 90° V6, 3/8"-16 thread.
  • Gold zinc finish adds corrosion resistance over plain steel bolts.

Description

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.

Installation

Q&A

What size are these bolts?
This kit includes twelve 12-point intake manifold bolts with matching washers and an installation wrench. Each bolt features a 3/8"-16 thread and a 1-inch length.

Does this kit include a wrench?
Yes. The kit includes a wrench sized for the 12-point bolt heads, so you have the specialty tool needed to install or remove the bolts.

Will this fit a Gen II LT-based small block?
Yes. This bolt kit is compatible with GM Gen II LT-based 265 CID and 350 CID small block V8 engines.

Can this be used with a GM 90° V6?
Yes. This kit also fits GM 90-degree V6 engines, including the 200, 229, and 262 CID applications.

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.
