Common questions

Will these cylinder heads work with my S&S compression release?

No, S&S compression releases controlled by a starter relay do not work with stock Harley-Davidson ACRs controlled by the ECM. Attempting to wire them together will damage the heads.

Yes, these S&S Cycle Super Stock cylinder heads are designed for stock displacement engines and are also ideal for stroker or big-bore builds up to 110 cubic inches.

What models do these cylinder heads fit?

These cylinder heads fit 2008-2016 Harley-Davidson Touring engines with stock crankcases. Please confirm your specific model year and engine configuration before ordering.
