Lingenfelter in house CNC ported GM LS3 aluminum cylinder heads can be used on 2008-2012 production 6.2L based Chevrolet Corvettes and various 2007-2012 L92 L76 6.2L and 6.0L based GM trucks.
Lingenfelter LS3 CNC ported complete cylinder heads are sold with light-weight hollow stem intake valves and heavy duty inconel exhaust valves that designed to be durable even under extreme high temperature conditions seen with supercharged or turbocharged applications.
LS3 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.
