S&S Cycle #106-3227 - Cylinder Heads - 79 cc - Super Stock® - Twin Cam

These S&S® Super Stock® high performance cylinder heads are designed for stock displacement or slightly modified 2006-'16 engines up to 110". The 79cc combustion chamber provides a significantly higher than stock, but still manageable compression ratio. Machined for S&S® electric or manual compression releases. The moderately sized 1.940" intake and 1.575" exhaust valves maintain port velecity in smaller displacement engines for good low and midrange response. S&S® High performance valve springs allow the installation of camshafts with up to .650" lift. Compatible with stock rocker boxes, exhaust, and intake manifolds. Silver powder coat finish matches stock silver engine components.
 
NOTE: Super Stock heads will not work with S&S compression releases in a late model twin cam that has HD® ACR's already installed. S&S compression releases are controlled by a starter relay but the stock HD ACRs are controlled by the ECM and they do not work together properly.  Damage will be caused to the heads and engine if customer or dealer tries to tie into the HD® wiring.
