Sorry the previous picture was after some cleaning. This pic is immediately after I pulled the head. The block was milled and I did put my straight edge on the block but I could only get one angle foe measurement, again .002" gauge couldn't get under anywhere. Preignition is possible as I was tuning the carb (Edelbrock 1407) up until this point, I definitely did hear pinging initially before I did my adjustments.
So can I chalk this up to bad carb tuning and throw everything back together?
