The main purpose of having the dowel on the crank in this position is to ensure that no pistons are at, or near TDC. This is so that you don't have any valves kissing pistons, just in case you have some sticky lifters that don't compress from being in the "relaxed" position, once you happen to torque down a rocker arm/pushtube assembly that happens to be in the partially open position.
