340 6 pack intake
Here are the two non-pristine areas.
The first is a hole that by all appearances got stripped out by a PO, then re-tapped off center. It could be run as-is, or if it bothers you it could be filled and drilled/tapped back on-center.
Here is the weld repair, at the front edge of the center carb base, just above the part number.
If you are interested in this, send me a PM.
