Proflow offers a variety of header flange sizes and shapes to mate your heads and headers. These 3/8 thick flanges are precision-cut to meet your ports, reduce warping, and prevent leaks. Proflow header flanges keep your tubes in place without the big price tag. This new Header plate is designed to fit primarily cast iron and aluminium aftermarket style heads with a 5/8"spark plug. This design allows for the plate to be reversed for best orientation with your exhaust port. Will not fit 13/16 socket early iron heads unless plates are cut to build individual primary pipes that can then slide into a merge collector for easy fitting Proflow graphite laminated stainless steel gaskets offer superior sealing capabilities, are non stick, comfortable with high temp and pretty much the best choice to use for sealing your pipes. They do not require any sealant and in most cases are useable Note: Gasket to suit PFEEHPFD3
