Edit: could be little of topic...but.
I´ve reused several of my 1.9 headgaskets and I´m still running 30-35 psi of boost afterwards. And I must say it works great!
A experienced friend of mine which builds race engines told me to stop buying new expensive headgaskets when all he did (if the gasket wasn´t totally screwed up) was putting a thin layer of spraypaint on each side to fill in the small scratches etc.
I always use new headbolts each time when putting it all back together again.
Don´t hate on me for doing it before trying it out yourself. It works! :twisted:
