I have to remove the heads and intake off my moms 70 Rallye 350. Only issue I’m having is with the vacuum lines, someone has plugged, bypassed and left a few hanging loose. I’d like to get them hooked back up the way they used to be. That includes the water temp controlled unit that’s in the front of the intake. Any help would be appreciated. Another question i have is can i remove the heads and leave the manifolds attached to the exhaust pipes? *edit* it’s a four barrel carb, air conditioning car.
