Near new DRD heads available for 94mm motor. 43cc chambers. Port matched manifolds for 48IDAs and another matched set for 48 IDFs. These heads made 170+ hp on a conservative engine dyno and with a 10.5:1 compression ratio. The heads have the standard length valves. Great setup for a hot street motor with the right cam and rocker combo. $2000 new. Make me a good offer. They may be seen at Ray Vallero's shop. They are in a box in the office.
