If anybody out there has a Performer RPM Air-Gap laying around, can you measure the length and depth of the plenum divider notch? Would really appreciate it.

The notch size is nothing special, every combo will want something different, especially depending on what carb is on top. Btw some people fill in that notch and get better results... As already noted its not easily filled and may NOT be a good move. I'd try a half inch spacer if space is tight.
