Lingenfelter CNC Ported LT4 Cylinder Heads - Pair

Product Details

---

LT4 cylinder heads are precision CNC machined on our in house 5 axis CNC machine to ensure that tight tolerances are maintained. The Lingenfelter CNC porting procedure is a computer controlled machining operation that duplicates details from a finished Lingenfelter hand ported cylinder head. The port and chambers are carefully designed to provide the best combination of high flow capabilities across the entire valve lift range. The Lingenfelter quality control procedures include sectioning sample cylinder heads to confirm minimum wall thicknesses.

Following porting each head receives: Precision 3 angle valve job to maximize flow & provide extended life, CC checking chamber size for correct compression, surfacing to insure deck flatness, deburring, pressure testing, professional assembly, setting spring height & checking all tolerances, and serial number.

Parts included:

• Lingenfelter double valve spring kit L230075897
• Lingenfelter titanium spring retainers
• Lingenfelter valve locks, seals & spring seats
