ok well i went to change the head to a z6 noticed cly 2 had pitting all over the pistons all the others are perfect just #2 ?? what could cause this and does anyone have any pictures of their pistons like this? help why just #2???!!@!#!

 

#2 fuel injector is screwy maybe?? I dont see a pic currently but i would assume its because of lean condition....what did the plugs look like??
