91cc heads for S&S 4-1/8 inch bore V-Series engines in 1984–1999 Harley-Davidson® big twins. By changing the profile and shape of the cooling fins, significant reduction in the transmission of mechanical noise was found. This not only benefits our TUV certified engines and EPA approved engines, but all of our performance engines as well! Since April 1, 2007 these redesigned heads have been being installed on all S&S 4-1/8 inch bore engines. 2.000 inch intake and 1.605 inch exhaust valves. Chosoe finish.
