360 Plug help

What carb is it exactly, part number. So you can see if it supposed to have screw in bleeds. The quality control was so bad, getting one where they skipped installing the air bleeds isn’t out of the question. Good design, but put together by a blind ham fisted monkey! When I was playing with mine, the FBO tuning book was worth the $15. Very methodical. I have only been playing with an AVS for 10 years, can’t remember much with a Holley based carb.
