Good Morning,

I am going through this holley 3310-6. What is the significance of the ring shown in the photograph? Is it wise to remove this ring and blend it smooth?

Thanks,

Bryan

If you are after max air flow, then remove it.
If you wish to have the carburetor work correctly without other modification, leave it there.
