TooHighPsi two-piece billet valve covers are designed for GM Gen V truck and SUV direct-injected V8 engines. They provide the injector and fuel-rail clearance required for compatible KATANA and VINDICATOR port-injection plates while supporting Magnuson 2650 and other intake or supercharger combinations.

Full internal baffling provides OEM-style oil control. Each cover includes a -16 ORB oil-fill port and a -10 ORB breather port. The included truck-coil spacer kit provides correct fitment for compatible GM truck ignition coils.

Compatible engine families: L83, L84, L86, L87, L8T and L8P.

Select: finish and integrated coil-mount configuration. Current anodized-product lead time is approximately two to three weeks.

Package includes: left and right billet valve covers, one oil-fill cap with O-ring, two breather fittings, valve-cover hardware, coil-pack hardware, valve-cover-to-head hardware and one truck-coil spacer kit.

The application-specific dipstick bracket and heater-hose hardware are sold separately.
