I have casting numbers from what I have been told is a 429 Cobra Jet 1970. Can anyone help to verify that the following numbers off of the heads is a Cobra: DOVE-A

Cole is right, not Cobra-Jet. These are sometimes referred to as Thunder-Jet as they were commonly used on Thunderbird engines. Closed chamber with standard size ports and valves, not the monster sized Cobra-Jet ports and valves. Good place to start, however, especially as an upgrade for 73-up smogger head engines.
