My plan to modify my system is to change up the vacuum configuration a little. I have enough vacuum to make the actuators work as oem, but the switch leaks a little, and it's stiff anyway, so my plan is to mount a dcv up on the rad support somewhere, and tap the headlight circuit to feed the 12vdc valve actuator. This allows me to run one vacuum source to the valve, and it'll be defaulted to the closed position, and when headlights are turned on, it'll shift the valve and apply opening vacuum to the actuators. About a $10 valve,with 100% duty cycle, and nothing that can't be changed back later.
This requires no modifications to the mechanism but might work a little better?
