CID-LT1/LT4 BARE CYLINDER HEADS WITH VALVE AND SPRING OPTIONS

CID CNC PORTED CYLINDER HEADS FOR GEN V LT1/LT4 APPLICATIONS

These CID cylinder heads come from Gwatney Performance with LT1 spec intake and exhaust valves and a 55cc combustion chamber on the LT1 castings, while LT4 spec intake and exhaust valves and a 62cc combustion chamber are offered with the LT4 castings. When you add a BTR spring kit to these, you will get a combination that will close in on the 700hp mark naturally aspirated with a properly sized camshaft and intake manifold.
