Peterson Fluid Systems pfs09-1064

The Peterson end rail spacer .500 kit fills the space between the manifold and the lifter valley end rail when using raised-port heads. Supplied with a spacer for the water pump and distributor ends plus four 3/16" roll pins to secure them to the block, the .500-inch thickness offers a larger clearance correction for compatible engine builds requiring that offset.
