NOTES: By changing the profile and shape of the cooling fins on our heads for 4 1/8" bore engines, a large reduction in the transmission of mechanical noise was found. This not only benefits our TÜV certified engines and our EPA approved engines, but our performance engines as well! Since April 1, 2007, these redesigned heads have been installed on all S&S 4 1/8" bore engines and Hot Set Up Kits. Replacement heads of the old style are available by special order.
