Includes Super Stock™ heads, T2 crankcase, high flow oil pump, cam cover and easy start 585 gear drive cams for reliable, street-ready performance.

Special head machining fits stock-length intake manifolds (S&S manifold size 405) and maintains a stock-style breathing system compatible with most factory and aftermarket air cleaners.

No fuel system or ignition components are included; select the fuel and ignition systems that match your application and tuning goals.

Revised oil routing on '99–'06 Touring models removes the need for an oil line installation kit, and cylinder heads are '99–'05 style—'06 owners may need to purchase '99–'05 style offset intake flanges as noted.
