<VV> Carb Adjustment

Santa brought me two new (rebuild) carbs for my '65 110 hp Monza.  Never being
one to leave well enough alone, I disassembled the carbs to check settings (I
also wanted to install 0.052 jets).  When I put the first carb back together,
I followed the procedure described in the Tech Guide (and in the shop manual)
for adjusting the fast idle cam.  The procedure calls for a 0.078 in. gap
between the idle speed screw and the throttle lever (with the idle screw in
1&1/2 turns and the fast idle tang on the second highest step of the cam).  My
gap was somewhat less than 0.010 in. so I attempted to bend the throttle lever
tang to increase the gap to 0.078 in.  This resulted in a quite "distorted"
tang that appeared abnormal.  When I put the second carb together, I carefully
measured the gap without any bending.  It was 0.007 in.  When I checked an old
carb (with a normal-looking U-shaped tang), the gap was approx. 0.040 in.
Have I missed something or should the tang really be bent enough to increase
the gap distance to 0.078 in.?

Recommendations are certainly welcomed.
