Intake Manifold Dilema

Dusterb, you do make a good point. Will a square bore carb hook directly to the M-1, or do I need an adapter? I notice it has the spread bore reliefs.

AdamR, I thought about just running it in and forgetting about it, but I don't know if I really want to "make it work". I definately don't want to TIG it. But thanks for the input.
