Product Details

Lingenfelter offers a CNC ported version of the L98 D port aluminum cylinder head used on the 1988 - 1991 Corvette L98. This head is suggested on any GM TPI engine 1985 – 1993. The port and chambers are carefully designed to provide the best combination of high flow capabilities and improved port velocity. This combination provides excellent horsepower gains while maintaining a strong torque curve. Lingenfelter L98 D port cylinder heads are precision CNC machined in house to insure that exact tolerances are maintained. The Lingenfelter CNC porting procedure is a computer controlled machining operation that duplicates exact details from a finished Lingenfelter hand ported cylinder head. Hand porting is a very labor intensive and time-consuming procedure that takes years to perfect. By CNC porting the cylinder heads the high cost of hand porting is reduced, plus the CNC porting is more consistent and will produce better results. Each CNC ported cylinder head will have the exact same port and chamber configuration as the original master used to develop the CNC program. 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, professional assembly, setting spring height & checking all tolerances. Base price package includes: 2.00 stainless steel one piece intake valves 1.56” stainless steel one piece exhaust valves, double valve springs for 74211 or 74219 camshaft, titanium retainers, 10 degree locks, valve seals, guide plates & ARP screw in studs. This product is priced using customer cores.
