I didnt think it would but this guy used a 179 head becuase his engine builder said he couldnt garantee much of a power increase using the black head, quite different he has a black block and told me that the black block has a higher grade of iron, he has a vk manifold on the 179 head and uses a 179 balanced steel crank becuase his engine build told him the lighter crank would rev quicker, apparently the builder has a lot of experience in racing.
its kind of like using the opposite to everything I am using.
here is a link to his site about his car.
