Description:

The RFD BBC-BILLET promises to be one of the baddest Big Block conventional heads available. Designed around raised intake runner locations with the floor of the port as much as .900" off of the deck depending on port design.

Designed primarily for Truck Pull, Turbo & Blower applications on alcohol, it's the STRONGEST BBC head available. The RFD-BBC BILLET features several options to suit your application and combination. High airspeed ports and very high flow rates make this one of the most powerful conventional heads produced.
