P1 Chevrolet LS Head Stud Kit – Gen 3 (2003 & Earlier), Two-Length Stud Set, 12pt Nuts, E190 Series, Black Oxide
PN# K003-H05E

The P1 Chevrolet LS Head Stud Kit for early Gen 3 engines (2003 and earlier) is engineered to deliver reliable clamping force and long-term sealing performance in high-output LS applications. Featuring two different stud lengths to match the original LS architecture, this kit ensures precise fitment while improving block and cylinder head stability under extreme cylinder pressures.

Manufactured from our premium E190 material — rated at an impressive 190,000 psi ultimate tensile strength — these studs provide exceptional durability, thread integrity, and resistance to stretch during high boost, high RPM, and high heat cycles. The black oxide finish adds corrosion resistance, while the included 12-point nuts and hardened washers deliver consistent torque transfer and uniform loading across the deck surface.

This is the ideal head fastening upgrade for naturally aspirated, boosted, nitrous, and endurance LS builds requiring greater reliability than OEM hardware can support.

Key Features:

  • Designed for Gen 3 LS engines (2003 & earlier) using two different stud lengths

  • E190 Series material with 190,000 psi UTS for strength and stability
