Minor bending may not alter the sear geometry but major will. Also the rear pin may need to be retaped and a new one made. It is all angles. The pin is made for a lower tang angle and the relationship of upper and lower will change. Say the hole is tapped at 85 degrees and after the bend is now 80 degrees so the pin will fit only if forced. To fix correctly I had a new pin made and hole retapped. The sears needed a little attention but I got lucky there. Your luck may be different.
Chuck gives good advise a out drawing it out on paper and see the lines. If you are trying to raise the comb by more than half an inch either the lines get weird or the tangs may have to be bent.
