Frequently Asked Questions

Can I use these heads with my stock Harley ACR (automatic compression release)?

No. S&S compression releases are controlled by starter relay, while HD ACRs use the ECM — they do not work together. Do not tie into HD wiring or engine damage will result.

Do these heads work with S&S compression releases?

Yes. These heads are machined to accept S&S electric or manual compression releases, which must replace the factory ACR system.

Will these fit my 2017+ Milwaukee-Eight Touring?

No — this part is for 2008-2016 Twin Cam Touring models only. Milwaukee-Eight engines require a different head assembly.

What compression ratio do I get?

Significantly higher than stock thanks to the 79cc chamber, but still manageable without requiring premium fuel in most applications. Dyno testing recommended.
