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.
Standard Ford 289 and 302 small-blocks were factory-rated between 200 and 230 hp. The vaunted 289 High-Performance engine was said to make 271 hp.Today, if a 302 Ford makes 360 hp on pump gas with a hydraulic cam, most experts consider it to be a pretty good motor-at least until Joe Sherman steps up to the plate.f you have a 289, Sherman says a 302 crank's 0.130-inch-longer stroke is worth at least 15 lb-ft of torque. Because 289 cranks and rods are getting rare while 302 components are as common as sand on a beach, a local crank grinder should be more than happy to trade 289 stuff for 302 parts.
