    When having the manifold log milled just be sure to let them know what carb you are using and that you want the log opened up so the hole is the same size as the adapter you will be using. Some prefer the 2x1 adapter for the Holley/Weber but the biggest gains are from the 2x2 adapter for the 2100 carb.
