stripped headbolts!

[heavyd]

so im unbolthing my head today and the socket slipped! on 2 different bolts... the bolts arent completely stripped, i just turned it once and it slipped so i stopped, what do i do to get these last 2 out without damaging them anymore?

id get an 11mm allen socket and hammer it in, then try it. after that youd have to clean the area with carb cleaner and get a bolt the the threads fit just inside the 10mm allen hole, then have it welded to the head of the stock headbolt. just make sure you use a grade 8 or stronger bolt for this, or itll just break and youll have to weld a new one.

make sure the bolts are really clean and try tapping a 10mm really good into it before trying an 11mm. thats all i had to do when removing heads.
