Inspect these areas for damage and fix it where necessary also chase threads with brake cleaner or clean thread holes in head bolt holes to produce right torque readings. Put new gaskets over dowels in block; then put these heads back without moving gaskets very much. Use thread locking compound to cover threads for new 8 mm head bolt(s). Then tighten these new 11 mm head bolts according to torque specifications followed by angle of rotation specified sequence having previously installed them finger-tight onto these newly coated threads with this substance named thread lockers.
