They work well with engines of stock displacement , but are ideal for somewhat larger stroker or big bore engines up to 110\". The 89cc combustion chamber provides a slightly higher than stock, but still manageable compression ratio in larger than stock engines.This makes them a good choice for touring bikes and other heavy vehicles. Machined for S\u0026amp;S® electric or manual compression releases. The large 2.000\" intake and 1.605\" exhaust valves maintain port velecity for good low and midrange response, but supply enough air for slightly larger engines to perform to their full potential. Intake ports flow 264 cfm compared to stock heads at 182cfm. 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. Wrinkle black powder coat finish matches stock black engine components.\n\u003cul\u003e\n  \u003cli\u003eS\u0026amp;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.\u003c\/li\u003e\n  \u003cli\u003eSuper Stock heads will not work with S\u0026amp;S compression releases in a late model twin cam that has HD® ACR's already installed.\u003c\/li\u003e\n  \u003cli\u003eDamage will be caused to the heads and engine if customer or dealer tries to tie into the HD® wiring.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe S\u0026amp;S Cycle 08-16 Touring Super Stock 89cc Cylinder Head Kit is engineered for Harley Davidson models from 2008 through 2016, offering enhanced performance while maintaining compatibility with stock crankcases. Designed to work optimally with engines of stock displacement, these heads are particularly ideal for larger stroker or big bore builds up to 110 inches, providing a significant boost in airflow and combustion efficiency. The 89cc combustion chambers deliver a slightly higher but manageable compression ratio, making these heads suitable for touring bikes and heavy-duty vehicles that demand reliable power and durability. They are machined to accommodate both electric and manual compression releases, offering flexibility for various ignition setups. The large 2.000-inch intake valves and 1.605-inch exhaust valves promote excellent port velocity, ensuring strong low- and mid-range response while providing sufficient airflow for larger engine configurations. Intake ports flow up to 264 cfm, significantly outperforming stock heads at 182 cfm, which translates to improved engine breathing and performance. Equipped with high-performance valve springs capable of supporting camshafts with up to .650-inch lift, these heads allow for further customization and power gains. Their wrinkle black powder coat finish matches the stock engine components, offering a sleek, high-performance appearance. Compatibility extends to stock rocker boxes, intake, and exhaust manifolds, simplifying installation and integration into existing systems. Please note that these heads are not carb approved and require carburetor acknowledgment during installation. They are suitable for a range of touring models, including Road King, Electra Glide, Street Glide, and Road Glide from 2008 to 2009. Proper installation and wiring are essential, and care must be taken to avoid wiring conflicts with existing Harley Davidson compression releases to prevent engine damage.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned for 2008-2016 Harley Davidson touring models with stock crankcases\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOptimized for large stroker or big bore engines up to 110 inches\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e89cc combustion chamber provides higher, manageable compression\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMachined for electric or manual compression releases\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLarge 2.000-inch intake and 1.605-inch exhaust valves for improved airflow\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIntake ports flow up to 264 cfm for enhanced performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-performance valve springs support camshafts with up to .650-inch lift\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with stock rocker boxes, intake, and exhaust manifolds\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eWrinkle black powder coat finish matches stock engine components\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eNot carb approved; installation requires carb acknowledgment\u003c\/li\u003e\u003c\/ul\u003e","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":47978842652930,"sku":"664063","price":1995.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0818\/3401\/7026\/files\/23b9ccd42f4bcd93d5e2fd0c6d0abd13.png?v=1781173554","url":"https:\/\/teamkustom.shop\/products\/s-s-cycle-08-16-touring-super-stock-89cc-cylinder-head-kit-wrinkle-black-for-harley-davidson","provider":"Teamkustom","version":"1.0","type":"link"}
