I'd either buy a vacuum guage (the're really cheap) or rent or borrow one and get a reading instead of guessing. That really lopey idle comes in large part from overlap and overlap is what causes a large percentage of vacuum loss. So it stands to reason if you have a really lopey cam you aren't gonna have much idle vacuum. Then again there are many other things that could be causing your problem, but i'd say first step is to find out what your idle vacuum is.
