Frequently Asked Questions
Can I mix these parts with another camshaft or valvetrain brand?
Only after confirming dimensions, materials, installed height, spring pressure, lift capacity, and geometry for the complete combination. Similar-looking components are not automatically interchangeable.
Do valve springs need to be checked before installation?
Yes. Measure installed height, seat and open pressure, coil-bind clearance, retainer-to-seal clearance, and maximum lift for the exact cylinder head and camshaft.
Should valvetrain components be replaced as a complete set?
Follow the engine builder's inspection and measurement results. Worn mating components can affect geometry and durability even when only one part is being upgraded.
Installation Instructions
Follow current GSC Power Division instructions and the vehicle service manual for part number 1006. Have a qualified engine builder inspect the cylinder head and mating components, perform required machining, measure every specified clearance, verify timing and free movement, and use the correct lubrication, fasteners, torque procedures, and clean assembly practices before startup.
