they dont look too bad, My 383 NA always burned plugs like that and I was dialed in at 12.6 AFR a tad rich for NA but it liked it.
A nice brown colour is usually perfect, wouldnt know on a turbo car tho.
Whats your timing and PE/VE tables like? did you modify so at 95KPa up drops timing and adds fuel etc?

stock range is autolite 105's the 103's are two steps colder. A bunch of different people told me their car runs better on the autolites. I havent tried the NGK's because the plugs do not foul out and the car pulls hard with no signs of detenation.

I believe 106 is the stock AL. I run the 104 which I always thought was two ranges colder. 103 may work good too, but pretty sure that's 3 ranges colder. As was mentioned, you want the copper core version, not platnium.
