Oversized Titanium Molybdenum Intake Valve Designed for LT1, LT4, and LT5 Custom Machined Cylinder Head Applications 

The Katech LT1/LT4/LT5 2.205" Big Valve Molybdenum Titanium Intake Valve is designed for LT1, LT4, and LT5 cylinder head applications requiring an oversized titanium intake valve with LT1 length for increased installed height. Manufactured from lightweight titanium, this valve is intended for performance valvetrain combinations using LT1 valve spring kits.

This valve features a 2.205" head diameter, 5.200" overall length, an 8mm stem, and a .252" tip. The LT1 length configuration provides increased installed height while maintaining compatibility with appropriate valvetrain components.

Each valve features a Chrome Nitride coating along with a back cut stem with molybdenum coating to provide enhanced wear resistance and durability. The non-steel tip design requires a lash cap, the same as stock.

Important!  Requires custom machining to work on LT1/LT4/LT5 heads.  Recommended for use with bronze valve guides.
