No they won't work all that well unless you use a T junction in line. Actually, 
using a vacuum gauge to set this up isn't all that effective as there's far too 
many variables in the system. Late valve timing, late ignition timing, leaking 
valves, low compression etc. all influence vacuum readings. Might be useful as 
far as getting some sort of optimum reading but that would be right at the very 
end of all your adjustments after checking timing with a strobe.
