S&S Cycle Super Stock Cylinder Head Kits
S&S Cycle Super Stock cylinder head kits feature stock-appearing cylinder heads with improved performance. These heads work well with engines of stock displacement but are ideal for engines with a little larger stroke or bore. They are compatible with stock rocker boxes, intake manifolds, and exhaust. The S&S high-performance valve springs allow for camshafts with larger lifts. Super Stock aluminum cylinder head kits are available in multiple finishes depending on application and they contain all the parts needed for installation except where noted.
