What is the primary benefit of these S&S Cycle cylinder heads?

These cylinder heads are designed for high performance, featuring larger intake and exhaust valves along with S&S Cycle's specific port designs to significantly improve airflow into and out of your engine. This allows for greater power output, especially when paired with other performance upgrades.

Do these cylinder heads come with everything needed for installation?

These cylinder heads are compatible with stock rocker boxes, exhaust, and intake manifolds. However, the manifold mounting surface is machined to stock dimensions, so if your engine height is not stock, you may need a special manifold or throttle body. It is always recommended to consult the manufacturer's installation guide for a complete list of required components.

Can I use these cylinder heads with my stock compression releases?

No, these S&S Cycle Super Stock cylinder heads are not machined for S&S compression releases. If your application requires compression releases, you will need to consider a different cylinder head option.

About this part

Product Details

If you're looking to get more out of your S&S T-Series T2 long block engine, these S&S Cycle Super Stock 91cc cylinder heads are a solid choice. They're specifically made for 2007-2016 Harley-Davidson big twin engines, and also fit 2007-2016 engines if you've installed the S&S 4-1/4" bore Hot Set Up Kit. These heads are designed to help your engine breathe better, which is key for making more power.

You'll find 2.000" intake valves and 1.605" exhaust valves here, which are larger than stock and work with S&S Cycle's own port designs to move a lot more air. The manifold mounting surface is machined to stock dimensions, but keep in mind that if your engine isn't stock height, you'll need a special manifold or throttle body. These heads also come with S&S Cycle's high-performance valve springs, rated to handle camshafts with up to .650" lift, giving you flexibility for further engine upgrades. They are compatible with your stock rocker boxes, exhaust, and intake manifolds, making installation more straightforward. The wrinkle black finish is a nice touch, matching the look of stock black engine components.

It's important to note that these cylinder heads are not machined for S&S compression releases. Also, they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding fitment and any required additional components.
