I've had good luck with screw in pipe plugs, though I did have to whittle on the one by the front oil passage, though that may have been overkill. Had to purchase a 3/4" pipe tap - a big sucker for a non-plumber.

The first time I did this I made the mistake of using aluminum pipe plugs. They worked fine, but when it came time to remove them I couldn't - the hex tool (which was the proper size) just distorted the aluminum. So much for saving a few grams. Now I use brass. Three plus the spray bar plugs are all I have ever felt were really beneficial.

JB welding externally to deal with oil weeping out past plugs is not the same as locating plugs which need to be removed to clean out gunk which might be in oil passages.
