Hi Mark,

I haven't used o-rings which came with the gasket set (it was a Victor Reinz set with blue o-rings), as consensus of opinion is that the blue ones are useless and just tear when tightening the bolt. Viton o-rings seem to be recommended by the forum, so those are what I've used.
With regard to the chamfers, only one half of the case has a machined chamfer the same as that on the washer, the bolt head side only as a counterbore and very small chamfer.
I'm now thinking about using the blue o-rings on the bolt head side, and the viton on the nut side. My thoughts are that if I can keep the bolt head stationary while tightening, the soft blue ring should be OK, and the tougher viton one on the thread side shouldn't tear as easily.
