These Ford Racing Performance Head Gaskets are specifically designed for use with cast iron or aluminum cylinder heads on a Ford 289, 302, 5.0L, or 351 Windsor V8 engine.
On some valves, like the Hayward SP714T, the spider gasket is glued into the bottom of the diverter, rather than inside grooves of the valve body. Leaking out the backwash line on this type of valve is more likely to be broken spring on the diverter stem, or debris stuck inside of the valve.n some valves, like the Hayward SP714T, the spider gasket is glued into the bottom of the diverter, rather than inside grooves of the valve body.
