I have a slightly different approach. I have marked my flywheel with a line of centrepunch marks 1 and 9/16 inches before tdc. (That is to the left of the 1/4 tdc mark on the flywheel when the engine is viewed from the rear). This equates to 20 degrees before tdc, which is the fully advanced timing. If I have to disturb the dynamo or distributor for any reason, it is a simple task to remove the flywheel cover, align the row of dots with the rear block securing nut, make sure the advance/retard lever is fully advanced, and arrange the distributor so that the points are just opening. It is possible to get the timing 180 degrees out,(been there and done that) but it is then just a case of rearranging the plug leads.
