do not re use the m11 cylinder head bolts!!!!!!get new m11 bolts do not apply anything to threads torque to 22ft lbs then second pass to 90 deg.torque patern from center alternating outward.....

final pass bolts 1-8 90 deg. and 9 and 10 50 deg.....9-10 are top bolts on each end........

m8 bolts apply thread lock to 5mm strip on threads.
then tighten the m8 bolts to 22ft lbs....begin with centre...alternating side to side working outward
