Detroit Diesel: The quest for easier starts

Since the Detroit 2-71 does not come with a cold weather start system, we have had to depend on starter fluid for cold weather starting. This morning was particularly bad, being sub zero (That's F), and we are out of diesel, so it was on veggie. I was looking at some glow plugs for a GM 6.2, and had a thought. There is a cover on the side of the engine that covers the intake ports on the lower cylinder walls. A couple of tapped threads in that cover plate for GM glow plugs might do the trick. At just under $10 each, it's a cheap experiment.
