PQY 12-Point Cylinder Gasket Head Stud Bolts Kit
The PQY kit is designed for 98-02 Camaro/Firebird and 97-03 C5 Corvette with 4.8L-6.0L GM engines. It features centerless ground, heat-treated studs and bolts to maximize reliability and strength, with nominal tensile strength around 220K psi. M11 studs are rated at 80 ft-lbs, M8 at 28 ft-lbs. The studs use iron with good ductility and a black oxide finish for heat resistance. Best for performance-minded LS builders seeking robust clamping and a straightforward installation.
- Best for: LS1/LS6 era engines and related trucks that require strong head-stud hardware
- Caution: Data indicates high torque targets; ensure engine block preparation and torque sequence are followed precisely

The 12-point design supports precise torque application and improved clamping force for reliable cylinder head installation. Best for: LS enthusiasts upgrading or building modern Chevy engines with robust head-stud hardware.
- Best for: Comprehensive LS installs with complete hardware
- Caution: Not a genuine OEM part; verify exact vehicle compatibility list before purchase
Buying Guide
- Engine compatibility: Confirm your engine family (LS1/LS3/LS6, 4.8L-6.0L) and model year range to ensure the kit’s studs, nuts, and washers match the required configuration.
- Stud geometry: 12-point vs. 6-point heads affect torque spread and clamping. 12-point designs often provide more accurate torque distribution and easier installation in tight spaces.
- Material and heat treatment: Look for heat-treated alloy steel or high-tensile iron with corrosion resistance. These features improve durability under high temperatures and boost reliability during boosting or heavy towing.
- Complete hardware: Kits should include studs, nuts, washers, and installation lubricant. Some bundles also provide gaskets or additional seals, which can simplify upgrades.
- Installation complexity: Some kits include detailed manuals and diagrams; others require advanced torque sequences. Consider your mechanical skill level and access to proper tools.
- Intended use: For diesel builds, prioritize kits with high clamping force and gaskets designed to resist blow-by under boost. For gas LS builds, focus on torque accuracy and compatibility with your cylinder head materials.
- Warranty and compatibility notes: Check vendor notes for vehicle compatibility, especially if the kit is marketed for Ford Powerstroke or Duramax engines. Some kits target non-LS platforms; avoid misalignment with your engine family.
Frequently Asked Questions
What is the main benefit of a head stud kit over a traditional head bolt set?
Head stud kits provide consistent clamping force and superior resistance to head gasket failure under high pressure and temperature, especially in boosted or towing applications.
Are 12-point head studs better than 6-point for LS engines?
12-point studs can offer more even torque distribution and easier alignment during installation, which can improve reliability in tight spaces.
Can I use a non-LS head stud kit on an LS engine?
Yes, only if the kit is explicitly designed for LS engines and matches the head stud geometry, thread pitch, and mounting pattern of your specific block and heads.
Do these kits include gaskets or only studs?
Many kits include studs, nuts, and washers; some bundles also include head gaskets or intake components. Always verify the exact contents in the product listing.
What should I consider when selecting a head stud kit for towing or boosted apps?
Prioritize kits with high-tensile strength, robust washers for load distribution, and high-temperature corrosion resistance. Verify torque specs and compatibility with your boost levels.
Is there a risk with installing upgraded head studs?
Improper torqueing and insufficient surface preparation can cause leaks. Follow the manufacturer’s torque sequence, ensure clean deck surfaces, and use the recommended lubricant.
