this is the sight of dohc...
I wondered how they did it for that engine. mercedes has had the overheads on v8s for a long time.

they must be confident with the alloys, at ten bolts per head.

a funny comparison, a 1781cc subaru boxer has 9 for one head, two cylinders.. if it were a mercedes v8, it would have 36 head bolts versus twenty...and it can still pop a gasket.

I guess I am saying, I don't trust the build by the sight of it..do you?
