ARP 154-4004 Pro-Series Head Stud Kit | Hex Head | Ford Small Block 351 Cleveland 351-400M | CHI 3V Raised Exhaust Heads

ARP 154-4004 Pro-Series Head Stud Kit — Ford 351 Cleveland with CHI 3V Heads

Factory head bolts stretch, lose clamping force, and can't be reliably reused. ARP's Pro-Series head studs are the benchmark upgrade for any serious 351 Cleveland build — providing superior, consistent clamping load across the entire head gasket surface for a seal that holds under sustained high-cylinder-pressure conditions.

This kit is specifically engineered for Small Block Ford 351 Cleveland and 351–400M engines fitted with CHI 3V cylinder heads (raised exhaust port version). The hex head design allows straightforward installation and removal without specialist tooling.

Features

• ARP Pro-Series construction for maximum tensile strength and fatigue resistance
• Hex head design for easy installation with standard tooling
• Superior clamping load vs OEM head bolts
• Reusable — studs maintain integrity across multiple assemblies
• Complete kit with all necessary hardware
