No vaccum to run headlights and grill in front ofwindshield
my headlights and my grill all operated on vacuum they all work perfectly the only thing I did was I change the spark plugs just of 327 a change the spark plugs and After I change the Slark plugs I don't have vacuum I've looked everywhere For a vacuum leak or of vacuum hose off or something but I can't find it any ideas

Welcome to the forum.
I don't know what year you have but there should be a vacuum Reservoir can somewhere that stores vacuum for short periods of time when you're at wide open throttle. I suspect the obvious location would be outside the frame rail behind the driver side front wheel. It's possible but that can has rusted out. If that's not it then the only other possibility I can think of is a hose that split or one that got knocked loose. If you have a small handheld vacuum pump, you could check directly on the grill over the wipers and the headlights. That would rule out that they both failed at the same time.
