So if I'm at 40Nm at the moment , have I still to go 90 - 90 ? (hardly budging any more + I would reckon there's no way the bolts could handle 2 x 90*i stand corrected...
autodata says
20Nm
40Nm
90*
90*
head tightening sequence is as follows
8 6 2 5 10
7 3 1 4 9 (flywheel side)
Its Alloy YC !The 899 head is cast iron much stronger than 1108. So a slight difference should not cause an issue .

Hi richy , So its a definite 40nm + 90 + 90 ?youll be suprised buddy they do go VERY TIGHT do you want a tip for angle tightening?
Hi richy , So its a definite 40nm + 90 + 90 ?
Other posts are of the opinion 30nm + 90 + 90 ?
The plot thickens ..
Thanks for reply whitz , so your also of the opinion 90 + 90 on top of 40nm will be ok oormaybe do one 90 and consider the other being the extra 10nm ?is 30nm +90 +90
and personally i dowt an extra 10nm will a dramatic difference

just goin on what auto data have published buddy
Stage 1: 20Nm
Stage 2: 40Nm
Stage 3: 90*
Stage 4: 90*
the wide majority says 30Nm+90*+90* for the 1108 head too but a punto 1108 head says 45Nm+90*+90* i did the latter when i did the HG in mine
