To get more bang for the
buck, choose the best quality of billet aluminum heads on the market. These head sets
offer increased horsepower and reduced detonation for the XLT 580, XLT and XCR 600
These billet head sets have cooling fins
machined in the top of the head, which offer more than twice the cooling surface. Also
developed is a much improved "O"-ring seal arrangement, there is no longer a
need to silicone the top "O"-rings. The bottom "O"-rings are made of a
high temperature Viton material for an excellent high pressure, high temperature seal. The
bottom and top "O" rings are also reusable.
There is no need to machine the head cover
plate in order to make it fit. This is a true bolt-on performance head set. A must for
modified or turbocharged engines, especially when burning oxygenated fuels.
