Manley 11612HB-8 Race Master Hollow Stem Intake Valve Set Ford 6.2L 54.5mm

Designed to meet the demands of bracket racing, oval track competition, and high-performance street builds, these valves deliver the precision and durability Manley Performance is known for.

The hollow stem construction reduces reciprocating valve train mass, enabling higher RPM capability and improved valve control compared to solid stem alternatives. With a 54.5mm head diameter and 0.3120-inch stem diameter, these valves are a direct fit for the Ford 6.2L platform featuring triple-groove keeper grooves.

Key Features:

• 54.5mm Head Diameter — optimized intake valve size for the Ford 6.2L cylinder head
• Hollow Stem Design — reduces valve train mass for improved high-RPM performance
• Stainless Steel Construction — intake alloy NK-842 stainless for outstanding heat and wear resistance
• Chrome Stem — enhanced surface hardness for reduced guide wear and long service life
• Hardened Valve Tip — resists rocker arm wear under sustained high-load conditions
• Swirl Polished Underhead — improved airflow through the port and past the valve seat
• Fully Machined Combustion Face — precisely controlled margin height for consistent sealing
• Triple Keeper Grooves — compatible with standard Ford 6.2L triple-groove retainers

Manley's Race Master series is the recommended choice for engines operating under 8,000 RPM in performance street, drag, and oval track applications. The 11612HB-8 provides a significant upgrade over OEM valves, supporting builds from mild street performance to serious forced-induction applications.
