Default exhaust discharge

i took the stang out last night to give her some exercise and when i got back i put it in the garage, left her running, checked to make sure everything is running correctly. no ticks, clicks, taps, nor drips. but i go back around to listen to my exhaust (my favorite part) and i noticed i can see a puff puff puff puff puff of smoke at idle. is this normal? when your looking straight on at the tail pipes you cant see it, but on an angle you can deff. see little bit of smoke coming out, but it disapates about 2 inches into the air. i cant tell if there is a color per say whether its white, grey, black or green? lol.

anything wrong? i know i'm have revving issues due to my springs on my heads, could this some of my problem? i dont have any power issues i dont think but i havent had it at normal condition since i bought the damn thing. so i guess i dont know what normal is. still has alot of power it feels like(puts me in my seat) other than that, i really dont think anything is wrong. is there?

Your valve seals may be dried out, and allowing a little oil to pass. This happens on a lot oncars that sit more than they run. Does it smoke more when you first start it (assuming it's smoke and not steam)?

nope, not smoke, steam maybe because i can see something coming out of the tail pipes but its transparent. when its warm it has a little more color too it but hardly cause you can only see it from certain angles. i'm assuming maybe your right with the valve seals. the heads are older than dirt. good thing they'll be replaced soon enough
