The reason it was align honed is because it was needed. It's part of the process of maintaining proper tolerances in the main caps. And when you align hone it sets the crank a few thousandths deeper into the upper mains requiring sometimes a undersized timing chain to take up the slack. That's the reason I had to go with a --5 Rollmaster timing chain. Taking a few thousandths from the main seal bridge by sanding it snugs up the loosesness left behind from the align hone.
