My experience with push types:
Some angle is inevitable.
Aside from compromising the angles, make sure the push rod contact to the slave's 'cup' has as much contact as possible and as much of that contact as possible should be at the bottom (center) of the cup.
If you start Mickey Mousing and miss-matching rods and slaves, you'll be more inclined to missalignment in the slave bore.
