The more bolts the greater the distortion....I have no confidence that this will work/seal if I use it.

Without seeing it "in the flesh", I think I'd be inclined to file out the two holes in the gasket right at the top, i.e. make them a bit oval downwards. From what I can see in that picture, the distortion seems to result from those two holes forcing the upper section of the gasket too far downwards.

 

Annoying when a part doesn't fit right...
