Peterson Fluid Systems pfs09-1065

The Peterson end rail spacer .625 kit provides a thick manifold spacer for raised-port head installations, closing the gap between the intake manifold and lifter valley end rail. The kit includes spacers for the water pump and distributor end rails along with four 3/16" roll pins to secure them to the block. Use the .625-inch spacer where that level of offset is required.
