Depending on how aggressive the cams are, that's entirely normal. I know on DSMs, they usually pull around 20" of vac, but with 272s it idles around 14-15". And you will usually have a lumpy idle.

i put a set of ca16de cams in mine and it does the same thing. i wouldnt think such a small change would do that but ive only got 2 vacuum lines and neither are leaking. my idle hunts from about 650-1100 rpm and ive only got ~16" vaccuum.

doesnt have to be vacuum lines, could be intercooler piping leak
