Engine & Cylinder Head Fitment

For compatible GM Gen V LT4 cylinder heads. Confirm valve dimensions, guide configuration, and spring installed height before ordering, particularly with modified or aftermarket heads.

Titanium or Tool Steel Retainers?

Katech recommends titanium retainers for drag racing. For street, road racing, and endurance applications, Katech recommends the appropriate tool steel retainer package instead.

Installation & Compatibility Notes

• Use Compatible OEM GM Valve Locks
• Inspect Existing Valve Locks for Wear or Damage
• Install Intake and Exhaust Retainers and Locators in Their Correct Positions
• Verify Spring Locator and Valve Seal Fit
• Measure Installed Height at Each Valve
• Check Spring Pressures Against the Camshaft Requirements
• Verify Coil Bind Clearance at Actual Maximum Valve Lift
• Check Retainer-to-Seal and Retainer-to-Guide Clearance
• Verify Piston-to-Valve Clearance for the Completed Engine Combination

The .670-inch lift designation does not establish clearance for every installation. Actual usable lift depends on installed height, coil bind clearance, and the complete valvetrain configuration.

Why Choose Katech

Bringing those parts together helps builders select a coordinated spring package while retaining the ability to verify the setup against their camshaft and measured cylinder head geometry.
