6 is the only one that looks like it's a little rich and the others look on the verge of lean.

unless you are running leaded gas, that is not long.  They look like they are seeing a lot of oil in the engine to me.  Is your car smoking on start up...wondering if the valve stem seals are leaking, or the guides are worn.

A lot of broken parts does not make you a racer; it makes you a slow learner.

Are these pulled from a running engine under normal conditions or did you yank them after a WOT pull?

Other than #6 looking a little rich everything is normal for a car running around stoich. Since I don't know your mods or idle AFR I really cannot comment beyond that.

Look at the ceramic and the electrode Larry. The ceramic on 5 look ok but 2 is a little spotty. 6 however has a dirty electrode and a very spotty ceramic tip. The spots can be oil or carbon but when it's on the electrode then it shows a rich condition.

and 28 is way too close!  I consider 032 too close unless you are making 700 hp or so, and I suspect the stock ignition is good for a lot more than that if it is getting full voltage....Too many cars making way over a 1000 hp have run stock.

And, it looks like the insides of the plugs are full of black goo which is why I asked about oil...might just be my eyes and the photo?

Today i pulled the plugs to re-gap them and they were completely black All OF THEM. I had to wire brush them before putting them back in
The car is rich as heck in idle And just driving around

if possible - once i get a "A" Wideband on the car i am going to ask Eric to use the files to lean it out some (A lot)

Was it a dry black or a wet black David? Not counting the threads here. :icon_smile:
