Description

PML makes a valley plate for the Buick Nailhead V8 in several models to accommodate various engine configurations. All valley plate models feature heavy duty construction for strength and fins for a classic appearance. Like all PML parts, our valley plates are sand cast aluminum and made in the USA.

PML offers two finishes: the natural cast finish and the polish finish. For the polish finish, the outside and top of the fins are polished but the area between the fins is not. This gives a better contrast and the fins stand out. Read about finishes and construction of PML parts.

Mounting bolts are included with all models.

Note For Engines With the Elco 3x2 Intake: The models with downtubes, part numbers 11081-2 and 11081-4, will not work with Elco 3x2 barrel intake.

Baffle For Models with Downtube and PCV Hole
