Description
The ARP 114-4203 head stud kit is listed for AMC 401. The fasteners secure the cylinder head to the block; their application, installed length and preload must work with the chosen head and gasket arrangement.
Technical Highlights
- Manufacturer part number: 114-4203
- Application/configuration: AMC 401
- Specified configuration: with Indy Cylinder
- Material: 8740 chrome moly
8740 chrome moly is a heat-treatable alloy steel used for strength and fatigue resistance in engine fasteners. Correct preload and joint preparation remain essential to the assembled connection.
Selection Guidance
Fastener preload supplies the clamping force at the head-to-block joint. Gasket sealing also depends on suitable deck finish, component condition and the correct assembly procedure.
Match the engine and any specified aftermarket cylinder heads or block to the listed configuration. Do not assume that related engines use the same fastener dimensions. Pay particular attention to the stated with Indy Cylinder configuration.
Installation Considerations
Check block threads, fastener engagement and cylinder-head clearance during trial assembly. Follow the instructions for this exact part number, including lubricant locations, washer orientation and tightening sequence. Washer seating and lubrication requirements vary by kit.
