P1 Honda B-Series & K-Series Head Stud Kit – 12pt Nuts, H260 Series, Plain Finish
PN# K050-H04H
The P1 Honda B-Series & K-Series Head Stud Kit is engineered for extreme-output Honda builds where maximum clamping force, head gasket stability, and long-term reliability are critical. Designed to support high-RPM operation, aggressive boost levels, and competition use, this kit provides a substantial upgrade over factory head bolts for both B-series and K-series engines.
Each stud is manufactured from P1’s ultra-high-strength H260 Series alloy, delivering exceptional tensile strength and resistance to stretch under extreme cylinder pressure. This material is specifically selected for small-bore, high-RPM engines where consistent clamp load and precise head-to-block sealing are essential for durability and performance.
The kit includes precision-machined 12-point nuts and hardened washers to ensure accurate torque application and even load distribution across the cylinder head. Finished in a plain (non-coated) finish, the fasteners maintain clean thread engagement and consistent torque values, making them ideal for professional engine assembly and competition use.
Perfect for turbocharged, supercharged, nitrous, or all-out naturally aspirated Honda builds, this head stud kit delivers the confidence needed to push the limits reliably.
