A friend (formerly ford guy...he's been turned!) just picked up a notchback barracuda with a mildly built up 383. It runs pretty good but there is a slight rpm lope at idle with a little shake, like it's loading up somewhat. For a ford guy by birth he's pretty good with carbs and tuning so he's been checking with no change. Stock rocker setup on the Eddys with a comp 280H cam. Not real bad but we don't think it should be doing it. We were looking at the pass. side head and when I layed a straightedge across the valves the #8 exhaust was sitting about .060 lower. Problem? Valve not getting the proper movement? If so does he need to yank it and install a longer valve or is a trip to the machinist in order. Or a lash cap on that one maybe? Thanks for input guys
