Product Details

Features

  • 35 chromoly studs deliver strong, consistent clamping for the 7.3L Godzilla
  • 12-point nuts with 3-step + dual 90° spec for accurate torque-down
  • Fits 7.3L gas Godzilla V8 only — not the 7.3L Power Stroke diesel
  • Complete kit built for Super Duty performance and Godzilla swap builds

Description

Upgrade your Ford 7.3L Godzilla gas V8 with this Pro Series cylinder head stud kit, engineered for stronger, more consistent clamping force and reliable head gasket sealing under higher cylinder pressure. Stud-style fasteners help guide the cylinder head into position during assembly for a more accurate, repeatable build.

Important: this kit is designed for the 7.3L Godzilla gas V8 only — it is not compatible with the 7.3L Power Stroke diesel, a completely different engine that happens to share the same 7.3L displacement badge. It's also not compatible with Coyote, FE, or Big Block Ford engines.

Manufactured from 35 chromoly steel with a black finish, these 12-point studs are built for demanding engine operation. Installation follows a torque sequence of 25 → 50 → 75 ft-lbs, followed by two 90° turns. Verify model year, cylinder head design, and gasket selection before installation.


Applications
Fits Ford 7.3L Godzilla gas V8: 7.3L/445 in³. Common on Ford Super Duty trucks with the 7.3L gas V8 and Godzilla swap/performance builds. Not compatible with the 7.3L Power Stroke diesel, Coyote, FE, or Big Block Ford engines.

Installation
Torque to 25 ft-lbs, then 50 ft-lbs, then 75 ft-lbs, followed by two additional 90° turns. Verify model year, cylinder head design, and gasket selection before installation.

Q&A

Does this kit fit the 7.3L Power Stroke diesel?
No. Despite sharing the same 7.3L displacement, the Power Stroke diesel is a completely different engine. This kit is designed specifically for the Ford 7.3L Godzilla gas V8.

Will this fit a 2022 F-250 with the 7.3L Godzilla engine?
Yes. This kit is designed for the Ford 7.3L Godzilla gas V8 used in compatible Ford Super Duty applications.

What torque sequence do I need to follow during installation?
Torque in three steps: 25 ft-lbs, 50 ft-lbs, then 75 ft-lbs, followed by two additional 90° turns. Follow the proper cylinder head tightening sequence during installation.

Will this fit a Coyote or FE Ford engine?
No. This kit is designed specifically for the 7.3L Godzilla gas V8 and is not compatible with Coyote, FE, or other Ford engine families.

Can I use this kit for a Godzilla engine swap?
Yes. This kit is suitable for 7.3L Godzilla swap and performance builds in addition to factory Ford applications.

What material are these studs made from?
35 chromoly steel with a black finish and 12-point nuts.

Will these studs work for a performance build?
Yes. The stud design provides consistent cylinder head clamping to help maintain head gasket sealing under the increased cylinder pressures found in performance applications.
