Lingenfelter offers a CNC ported version of the LT1 L86 aluminum cylinder head used on 2014-2015 production 6.2L Chevrolet C7 Corvette, 2014-2015 production L86 6.2 L based GM trucks.
LT1 L86 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.
