Default 1.6 rocker install update/question

I installed a set of Crane 1.6 roller tip rockers(after sitting the box for over a year) in my vehicle this afternoon. The idle is now on the lopey
side. I have the idle speed set at 700rpm. Will I need to make any other adjustments? My cam if I remember is 278/288 duration (adv)
414/442 Lift (not sure about the lift as I misplaced my cam card when
I rebuilt the engine)

Rockers too tight can cause the idle to be lopey.

I would suspect a vacuum leak assuming you have the rockers adjusted right.

-Mark.
