When I did the last 2 motors we assembled the bottom end and then honed down the surface to make sure the base gaskets layed on a smooth surface. Cometic has a special torque sequence that was done, and they were installed dry, but the motor was heated up to 145 degrees before torqueing . This was something we did on the race car motors.
Zinster I can not comment on the S&S motor. Have never ridden one so I can not compare
