Product Description

The TooHigh PSI Billet Valve Covers are a premium engine bay upgrade for GM Gen V LT1 and LT4 engines, combining race-inspired styling with the functionality required for serious high-horsepower builds. CNC-machined from 6061-T6 billet aluminum, these two-piece valve covers are engineered to provide increased clearance for port injection systems, aftermarket fuel rails, larger superchargers, and upgraded valvetrain components while dramatically enhancing the appearance of your engine compartment.

Unlike factory composite valve covers, the TooHigh PSI design incorporates full internal baffling for OEM-quality oil control, integrated ORB ports for custom crankcase ventilation, and optional coil mounting configurations to accommodate a wide range of performance builds. Whether you're running a stock LT4 blower, a Magnuson 2650, or a custom forced induction setup, these valve covers are built to support the airflow and packaging demands of modern LT performance.

Proudly manufactured in the USA, these billet valve covers are the perfect finishing touch for enthusiasts looking to build an engine bay that's as impressive as the horsepower underneath it.

Why Upgrade?

Factory LT valve covers work well on stock engines, but they quickly become a limitation on serious performance builds with port injection, upgraded superchargers, or custom crankcase ventilation systems. The TooHigh PSI Billet Valve Covers solve these packaging challenges while giving your engine bay a clean, high-end appearance that stands out at every car show and track event.
