S&S Cycle 08-16 Touring Super Stock 79cc Cylinder Head Kit - Wrinkle Black

This is the S&S Cycle Super Stock 79cc Cylinder Head Kit in a wrinkle black finish, designed for 2006 through 2016 Harley-Davidson Touring and Softail models. These heads are built to enhance the performance of stock displacement or slightly modified engines up to 110 cubic inches. The 79cc combustion chamber is key to achieving a higher compression ratio than stock, which translates to more power and improved throttle response, while still remaining manageable for everyday riding.

Inside, you'll find moderately sized 1.940-inch intake and 1.575-inch exhaust valves. This sizing is carefully chosen to maintain port velocity, especially in smaller displacement engines, ensuring good low and mid-range response. The kit includes S&S High Performance valve springs, capable of handling camshafts with up to .650 inches of lift, giving you flexibility for future upgrades. These heads are compatible with your stock rocker boxes, exhaust, and intake manifolds, making installation more straightforward. The wrinkle black powder coat finish is a nice touch, designed to complement the look of stock silver engine components.

It's important to note that these Super Stock heads will not work with S&S compression releases in late model Twin Cam engines that already have Harley-Davidson's Automatic Compression Release (ACR) system installed. Attempting to tie into the HD wiring can cause damage to the heads and the engine. If your bike has factory ACRs, you'll need to manage compression releases differently, either through S&S electric or manual releases, but not in conjunction with the stock HD system. This kit is a solid option for riders looking to significantly improve their engine's breathing and power output.
