ARP BMC B-series Head Stud Kit

The ARP BMC B‑Series Head Stud Kit is a high-strength fastener set designed to securely clamp the cylinder head to the engine block on BMC B-Series engines (commonly found in classic vehicles such as the MG MGB, MG MGA, and Austin‑Healey 3000). It replaces standard head bolts with precision-manufactured studs and nuts to provide more consistent clamping force, improved durability, and better head-gasket sealing—especially useful in performance builds or engines that are frequently serviced.

Features

• High-strength ARP material: Manufactured from premium heat-treated alloy steel for superior tensile strength and reliability.
• Improved clamping accuracy: Stud design reduces block thread wear and allows more precise torque application compared with bolts.
• Enhanced head-gasket sealing: Even clamping force helps prevent head-gasket leaks under high temperatures and pressures.
• Corrosion-resistant finish: Typically black oxide coated for durability and protection against rust.
• Complete kit: Includes studs, hardened washers, and 12-point nuts for straightforward installation.

Benefits

• Greater engine reliability in both stock and high-performance builds
• Reduced risk of head lift or gasket failure
• Easier cylinder-head removal and installation during maintenance
• Reusable fasteners when properly torqued and maintained

Typical Applications

• Classic BMC B-Series 4-cylinder engines (1.5L–1.8L variants)
• Restoration projects for classic British cars
• Performance or racing builds requiring stronger head retention
