Katech C7 Z06 Corvette K-Spec Series 800HP LT4 Heads and Cam Package
800 HP Supercharged LT4 Performance with Katech CNC-Ported Cylinder Heads, K-Force 2 Camshaft, and Upgraded Supercharger Drive System!
Engineered Heads and Cam Performance for the Supercharged GM LT4
The Katech C7 Z06 Corvette K-Spec Series 800HP LT4 Heads and Cam Package is a comprehensive performance upgrade designed to deliver 800 horsepower from the factory-supercharged GM LT4 6.2L V8. Combining the Katech K-Force 2 camshaft, Katech CNC-ported cylinder heads, upgraded valvetrain components, and an ATI supercharger drive system, this package is engineered to increase airflow, improve engine breathing, and support significantly greater horsepower and torque.
At the heart of the K-Spec 800HP package is the Katech K-Force 2 camshaft, paired with a 660-Lift Platinum Gen V LT valve spring kit, GM LS7 lifters, Trend pushrods, and supporting timing components. Katech CNC-ported cylinder heads further improve the LT4's airflow potential, while the ATI lower damper and supercharger pulley provide an upgraded drive configuration for the factory supercharger.
Designed for C7 Corvette Z06 owners seeking substantial performance gains without replacing the factory supercharger, the K-Spec package focuses on proven heads and camshaft modifications supported by professional calibration and chassis dyno work. The result is a more aggressive supercharged LT4 performance combination that retains the factory supercharger architecture.

The Katech Installation Process
Vehicle Inspection
Before performance modifications begin, the vehicle's condition and existing engine operation can be evaluated to identify concerns that may affect the completed performance combination.
Baseline Dyno Testing
Baseline chassis dyno testing is included to document vehicle performance before modifications and establish a reference point for evaluating the completed package.
Cylinder Head Preparation
The factory LT4 cylinder heads receive Katech CNC porting and basic cylinder head assembly service. CNC porting is designed to improve airflow through the cylinder heads, supporting the increased airflow demands of the K-Force 2 camshaft and 800HP performance combination.
Camshaft and Valvetrain Installation
The Katech K-Force 2 camshaft is paired with the 660-Lift Platinum Gen V LT valve spring kit, GM LS7 lifters, GM lifter trays, and Trend pushrods. These components support the increased valve lift and operating requirements of the upgraded camshaft.
VVT Lockout and AFM Modifications
The package includes a VVT lockout plug kit, Katech VVT lockout bolt, and AFM delete rivets for the engine block. These components support the camshaft conversion and modified engine configuration.
Supercharger Drive System Upgrades
The factory LT4 supercharger drive system is upgraded with an ATI lower damper, ATI supercharger pulley, and Gates supercharger belt. These components provide the intended supercharger drive configuration for the K-Spec 800HP performance combination.
Cooling System and Supporting Components
A Katech billet thermostat housing and 160-degree thermostat are included as part of the cooling system modifications. Additional supporting components include GM LT4 head gaskets, ARP head bolts, Brisk Racing spark plugs, engine seals, service fluids, and required hardware.
ECU Calibration
The package includes HP Tuners credits and ECU calibration services appropriate for the K-Spec 800HP heads and cam performance combination. Calibration is developed to support the upgraded camshaft, ported cylinder heads, modified supercharger drive system, and overall engine operation.
Dyno Calibration and Validation
Chassis dyno work is included to evaluate the completed performance combination and support calibration adjustments. Dyno testing provides an opportunity to assess engine response and performance following the modifications.
Street Calibration
Street calibration is included to refine throttle response, idle quality, part-throttle operation, and general drivability with the upgraded camshaft, cylinder heads, and supercharger drive system.
The Katech Difference
Katech Engineering has been developing, machining, assembling, and validating high-performance engines and components since 1977. From professional motorsports programs to premium street performance packages, Katech focuses on complete engineered systems rather than random combinations of parts.
The K-Spec Series 800HP Heads and Cam Package takes advantage of Katech's engine development, CNC machining, cylinder head preparation, and calibration expertise to deliver a cohesive supercharged LT4 performance combination.
By bringing together the K-Force 2 camshaft, CNC-ported cylinder heads, upgraded valvetrain, and supporting supercharger drive components, Katech provides a coordinated performance solution for the C7 Corvette Z06.
