Ok so I'm rebuilding my motor (1991 4G63 turbo) and tonight I got the head off in a couple hours, yes I know I was slow. I ended up getting pissed off and just cutting the vacuum lines going under the intake that go through that support bracket, but I remember a post a while back saying you dont need certain lines. I was wondering which ones? or if i could just rip em all out. There were two going to the coolant neck, one coming off the side of the intake by the fuel rail and I think 4 coming from the throttle body and 4 coming and going from a mount on the fire wall. Any input is greatly appreciated
 
The only vacuum lines I have on my car is the one going from the intake manifold to the fpr and boost gauge. I also have another going to the blow off valve and boost contol(then to wastegate). Hope that helps.:thumb:

It does help a lot! Thanks for the great info. I wont be needing it for a week or two while the block and head are out and while I'm reassembling the block but I will have to save all this. Thanks again
