Offenhauser single plane SB 360

If you can get the part number and or port size that would help.

The guy says he could find the part number but says the ports are 15/16 which is only 1/16 difference than my heads and i havent port match yet, so this sounds like a small port Offy.

What is the advantage/disadvantage to the single plane?
