    I'm just going from memory here Steve (and it's not the best) but I recall the 85 and 86 are different, where the 85 has a completely flat gasket face, the 86 has the half-moon projections. I think Big H changed the cam journal machining process between the years, which required full access from the outside for boring hence the half-moons, but gave a more reliably machined bearing surface.
