The Kooks Small Block Ford Yates flange is a mild steel bank flange with a 2.95in diagonal Yates bolt pattern and a round port sized for 2-1/8in primaries. Built from 5/16in thick mild steel and sold individually, it fits Yates-style small-block Ford header builds and provides a straightforward replacement or fabrication flange where that bolt pattern is required.
