carb vacuum

[zman]

Set the carbs with vacuum gage and could only get them balanced at around 27.
What are the implications of this if any thanks

Doesn't matter what the reading is as long as they are all the same.

As Rob says above, some small changes in cam timing amongst other things can explain differences in idle vacuum. A much lower value than 27 may give rise to poor idleing but i suspect yours' is as regular as anything. 22 springs to mind as a basline value for standard set-up.
