Head which looks like the studs have pulled into the head. Can catch the lip with my nail.

Dunno what to do now

Not run a MLS and use bigger lazer cut washers is a good start .....

E70, last time I was chatting with my tuner he runs them at 0.8 lamda and knows I am on e70.

If your referring to my dyno sheet that shows the graph leaning out on target boost I've never driven it on that setting through the boost controller.
