Description Navarro 59A Blower Heads 75cc have been the best flowing and highest quality head on the market since the late 1940’s. Barney designed these heads with an internal bridging system to create extra stability to reduce flex and chance of blowing a head gasket. He also designed a horseshoe style chamber which allows the motor to flow more freely. These heads are made from the highest quality 356 aluminum alloy from permanent patterns at the same 4th generation family foundry Barney Navarro has always used. The Navarro heads are a bolt-on item which will enhance the performance as well as appearance.
