Frequently Asked Questions

Will these work with my S&S compression release?

No — S&S compression releases controlled by a starter relay do not work with stock HD ACRs controlled by the ECM. Attempting to wire them together will damage the heads and engine.

Can I use these on a pre-2008 Twin Cam Touring?

This part is engineered for 2008-2016 Touring engines. Verify compatibility with your specific engine year and crankcase design before ordering.

What displacement engines do these heads support?

They work well with stock displacement but are ideal for stroker or big-bore engines up to 110 cubic inches.

Do I need to upgrade my intake and exhaust valves?

These heads ship with 2.000-inch intake and 1.605-inch exhaust valves. Consult your builder on whether upgrades suit your specific build.
