Carb Spacer help - what's on your intake

Before I used a straight 4 hole spacer I’d use this
4150 1" Shear Plate

Or this
Carb Spacer, 4150 1.750" Professional, dAMBEST Carburetor

I really like the damBest shear plate the best but the
Visner is really nice too and I bought it before I found the damnest piece.

Both are much better than just a 4 hole space. Although with a dual plane intake I’d call John at damBest and get his thoughts first. Or call Visner. They are very nice to deal with too.
