PRODUCT DESCRIPTION
Fits: Standard 383-400 port size
This valley plate is designed to work with standard Big Block port size, including ported heads or manifolds and is only 1/4 the weight of aluminum valley covers. They not only look nice, but they fit nice too!
These valley covers are designed to work with manifolds that DO NOT have a heat crossover passage that hangs below the intake port openings. That includes most single plane intakes plus the Indy dual plane. Dual plane intakes with the heat crossover passage must be modified to use our valley cover.
