Always start with the original shim stack height and add or subtract based on the checking distance difference between the old and new gearsets. That gets you to a really good starting point for the finer adjustments, sometimes ends up damn near perfect. I'm thinking it may be too late (did you keep the original shim stack intact to measure off of?). If so, just keep pecking at it and you will come up okay eventually.
