Supertech Valvetrain & Engine Parts

Shop Supertech engine-build components at Black Ops Auto Works. Explore intake and exhaust valves, valve-spring kits, guides, retainers, pistons and supporting hardware. Coordinate the selection with your engine builder’s measured specifications and complete cylinder-head or short-block plan.

Intake and Exhaust Valve Choices

Choose intake or exhaust valves by exact engine code, head diameter, stem dimensions, length, material and groove arrangement. Compare standard and oversized options using the cylinder head’s measured requirements. Coordinate any oversize selection with the builder’s machining plan, valve guides and seats before ordering the complete set.

Valve Springs, Retainers and Locks

Build the spring package around the camshaft and the cylinder head’s measured installed height, pressures and clearances. Single, dual, beehive and conical springs have different mating-component requirements. Check whether the selected Supertech spring requires its specified retainer, seat or lock, or explicitly supports the OEM components.

Guides, Seals, Lash Caps and Shims

Match guide material and all stated dimensions to the head and valve. Seals, lash caps, locators and follower shims require their own stem, diameter, thickness and mating-component specifications. Locks may require more than one piece per valve; confirm both package contents and total build quantity.

Pistons, Rods and Head Gaskets

Select pistons by bore, compression height, crown specification and the measured engine build. Check whether rings are included and select any required ring set to the piston’s exact groove specifications. Match rods by center-to-center length and mating dimensions, and choose head gaskets by engine, bore, thickness, side and required quantity.

Choose Your Part

• Identify exact engine code and the builder’s measured specifications.
• Coordinate valves, springs, retainers and supporting hardware as one plan.
• Review machining requirements, companion references and total build quantities.

Frequently Asked Questions

Are oversize valves direct replacements by engine code alone?

No. Match complete dimensions and the required head-machining plan.

Can every spring use the same retainer?

No. Follow the exact spring reference’s retainer, seat and lock requirements.

How do I check whether a Supertech piston set includes rings?

Review the exact piston set’s supplied contents before ordering. If rings are separate, match the ring set to the piston bore and groove dimensions and confirm the builder’s complete engine specifications.

Does a package quantity always equal the engine’s requirement?

No. Calculate the full build quantity from the component specification and supplied set size.

What helps review a Supertech order?

Provide engine code, measured build data, camshaft details and the complete proposed component list from the builder.
