Speedmaster SBC MLS Head Gasket Stud Kit Bore

The Speedmaster small block Chevy (SBC) multi-layer steel (MLS) head gasket and stud kit combines high-pressure MLS cylinder head gaskets with 12-point chromoly head studs. It is a complete head sealing and fastening solution for high-horsepower SBC engine builds. You may also see it called an SBC head gasket and head stud set, or an MLS head gasket and stud kit.

Key Features:

• Multi-layer steel gaskets: A high-pressure steel laminate design withstands the shearing forces between aluminum heads and cast-iron or aluminum blocks.
• Embossed sealing: Internal embossments expand with rising heat and pressure to maintain contact pressure for a reliable seal.
• Better torque retention: MLS construction resists distortion and holds torque better than conventional composite gaskets.
• .040 in. compressed thickness on the gaskets.
• 8740 chromoly head studs: Made from aircraft-quality steel, cold-forged, heat-treated before thread rolling, and rated at 190,000 psi.
• Black oxide finish on the studs.
• 12-point nuts and hardened parallel washers: Spread clamping load evenly and give accurate torque readings.

This kit suits nitrous, turbocharged, and supercharged builds, and other high-cylinder-pressure applications. Using the gaskets and studs together helps keep the cylinder head clamped to the block under demanding conditions. Choose the variant that matches your engine's bore size.
