These CNC machined adapters allow you to run a 427 SOHC valve cover on Gen 1 and Gen 2 Coyote engines. These adapters allow you to run factory variable valve timing. The bottom features an o-ring for sealing. The adapters are designed to use OEM seals for the spark plug openings and the VVT plugs. Each adapter has an AN threaded boss to evacuate crankcase pressure. The left side adapter features an oil fill location with a threaded cap and the right side adapter has the dipstick in the factory location.

SOHC valve covers will need to be sourced separately.
