2bbl to offy dual port questions....

Of course a performer rpm would yield better results but the offy is sitting on a shelf in my garage. I like cheap power lol

Should I throw a carb spacer on too?

Use a carb gasket like this with the divider in the middle. It will help keep the low end and mid range of the dual plane intake:
