using the correct back sequence I loosened and removed all the head bolts..

None were particularly loose to the other bolt 9 came out damp and grimly.

However when the head slipped off nothing screamed out failure at first.

Looking at the head however were 3 cracks on the cylinder around prechambers. So the head is toast.

Other than the pointed out blackspot near cyl 1 from what I can fathom it looks to be original and general worn out appearance rather than a warp or overheat.

Nothing on the old gasket stuck out either...

Much cleaning and preparation next though I'm out of razor scrapers and earplugs to plug the bolt holes...

cylinders seem fine with visible cross hatching and no ring lip.
25years and 250000km on the original head and gasket is not bad for these engines.
