OK, I was finally able to read the casting numbers. . .the passenger side was basically illegible no matter what, but the driver's side was easy to read with just a quick shot of engine de-greaser.

061. . .should be 1967 400 2BBL/4BBL heads with 72cc (or 75cc depending on what site you look at) chambers, press-in studs, and 2.11"/1.77" I/E valves if online sources are correct.

I also finally found the part number on the carb 1850-4 with 3145 below it. . .should be a Holley 4160 600 cfm with vacuum secondaries and a mechanical choke. Should be a good starting point for a relatively stock engine I would think.
