1966 Barracuda 273 Valve Covers Querie

The basic cover is the same. The 2 barrel and 4 barrel engines had the same adjustable rocker arms until 68. The HP 273's had the black wrinkle finish and the aluminum heat sinks from 65- 67 with different configurations of wiring tabs and stove pipes for pcv valves. Pretty much all small block valve covers will interchange.
