I had mine machined for a one piece seal, I also don't have shims. I am actually in the process of installing the engine this weekend, so I won't know how it works for a while. But I do know the rope seals don't work very well. Not like a good full seal does anyway. And $3000-$4000 is not real bad I wouldn't think.
