Not machined for S\u0026amp;S® compression releases. The manifold mounting surface specially machined to compensate for the slighty taller cylinders, so a stock length manifold\/throttle body will fit. S\u0026amp;S® High performance valve springs allow the installation of camshafts with up to .650\" lift. Compatible with stock rocker boxes, exhaust, and intake manifolds.","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":44401078010030,"sku":"SSC900-3249","price":1999.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0521\/0714\/9486\/files\/3eeffcbd2d346bf071a2144826fd4884.png?v=1702145471","url":"https:\/\/purauto.com\/products\/s-s-cycle-valve-spring-m8-2017-touring-collar-top","provider":"PurAuto","version":"1.0","type":"link"}
