buffer (bÅ­f'Ér) Chemistry A substance that prevents change in the acidity of a solution when an acid or base is added to the solution or when the solution is diluted.
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.
Depending on your engine and type of vehicle, the exhaust manifold can either be a set of pipes or it can be a cast iron manifold assembly. Essentially the exhaust manifold takes the burned exhaust gases from the engineâs cylinders and ejects the gas through the exhaust system and out through the car's tail pipe.The exhaust manifold gasket seals the surface of the exhaust manifold to the surface of the cylinder head, preventing leaks in the system.Over time, the constant expansion and contraction of the components (caused by constant heating and cooling in the engine), may cause the gasket to leak.ssentially the exhaust manifold takes the burned exhaust gases from the engineâs cylinders and ejects the gas through the exhaust system and out through the car's tail pipe.
