106-1071 Shovel to Panhead cyl. head conversion kit. 3-5/8"

For riders running a 3-5/8 inch big bore 1966 to 1984 Shovelhead, this S&S conversion kit provides the ultimate vintage transformation. You get the timeless look of Panhead rocker covers on a high-performance head assembly that retains the Shovelhead bolt pattern and exhaust mounting. Internally, the kit is all business, featuring an Evolution-style valve train with Evo hydraulic lifters, billet tappet guides, and S&S roller rocker arms. The included Quickee pushrods provide modern through-the-pushrod oiling for superior top-end lubrication. The heads arrive with valves and .590-inch lift springs pre-installed. To finish the build, you will need an Evolution Big Twin camshaft and an O-ring style intake manifold. This kit is the perfect blend of classic 1950s styling and modern S&S engineering for your big-bore Shovelhead.
