Item Details


Installation Note:

Due to the nature of the tight fit and the design of this manifold, on certain blocks, there may or may not be an interference with contact between the block and the back side of the manifold preventing installation of the manifold. Interference is very minimal when this occurs as an 1/8" to 3/16" of material may be necessary to remove from the block to alleviate the interference in certain instances. As such, this area of the block must be machined/material removed in order to allow for proper fitment and installation of the manifold.
