Here's a better shot of the timing cover. Notice that 2 of the bolts that hold the cover are recessed under the gasket surface and that 2 of the 318 water pump will clear. Also an oiler for the gear drive. It is for a 340, but just a little modification down near the bottom of the block was all that was needed to work. The bottom of the bracket had to have a little material removed to be flush with the bottom of the block, and a 5/16"-18 hole drilled and tapped inn the same region. The oiler will keep the idler bearing lubed. It sits in away from the face of the gears and I'm a little concerned that it will run dry or close to it anyway. The oiler has an .039" hole and should do the job.
