stock engine, kelford 272's @ -10...idle is at 1000rpm...

this seems to be the norm for people with these cams on stock engine?

should i be pulling more than -10 vac at idle? a couple people have told me i should get at least -15...but reading this thread sorta has me re-assured that i should be in the clear with my -10...
