Supertech Honda LEA1 / L15A1 Inconel Exhaust Valve - Set of 8, manufacturer part number HEVI-1050-8, is a new Supertech valves product. It is identified by the exact published engine-family, material, dimension, and package details in the product name. Confirm every current Supertech specification and the engine builder's required clearances before ordering.
Key Features
- The 23mm standard head diameter and dish face match factory port geometry, so this is a direct fit replacement.
- The stem diameter is 5.46mm, matching the factory LEA1/L15A1 valve guide specification.
- Each valve measures 117.55mm in overall length.
- The nickel superalloy construction is designed to resist heat fatigue better than stock steel valves.
- Many owners choose Inconel exhaust valves during a routine head rebuild simply for the added heat resistance over factory steel valves.
- Machined from a nickel based superalloy, HEVI-1050-8 valves resist the thermal fatigue and creep that stock exhaust valves develop under repeated heat cycling, making this set a common choice for owners refreshing a high mileage head or building for track use.
Fitment
Supertech Honda LEA1 / L15A1 Inconel Exhaust Valve - Set of 8 is engine-application specific. The current manufacturer evidence identifies an engine family or dimensional application but does not support a finite year, make, and model record for Convermax. Confirm the exact engine code, cylinder head or block configuration, dimensions, companion parts, and Supertech part number before ordering.

Frequently Asked Questions
How do I confirm Supertech HEVI-1050-8 is correct for my engine?
Match the exact manufacturer part number, engine family, dimensions, material, quantity, and every current Supertech application note. Do not select an internal engine component by appearance alone.
Can Supertech HEVI-1050-8 replace a similar-looking component?
Only when Supertech and the engine builder confirm every critical dimension, material, installed height, groove or seat geometry, clearance, and companion component requirement.
What should be checked when installing Supertech HEVI-1050-8?
Measure all relevant clearances, verify orientation and installed height, confirm companion parts, follow the current engine service procedure, and complete the engine builder's inspection before operation.
Installation
Professional engine assembly is recommended. Follow the current Supertech instructions and the exact engine service procedure. Clean and measure every mating surface, verify all clearances and installed heights, use the specified lubricants and torque values, rotate the assembly by hand where appropriate, and complete leak, compression, oil-pressure, and valvetrain checks before operation.

Titles distinguish standard or oversized valves, different materials and groove arrangements. Oversize choices require appropriate machining and a coordinated head build rather than selection as a direct replacement by engine name alone.Valve Springs, Retainers and LocksSingle, dual, beehive and conical references have different complete-system requirements. Some titles require a specific retainer, while others identify use with an OEM retainer or seat.
