I'm running his rebuild kit in my truck. Cut/delipped/coated pistons, stage 1 cam, etc. He was great to deal with and answered all my questions. The only thing I didn't like was that the kit came with aftermarket headgaskets so I bought two new ones from Ford. They probably would have been fine but I prefer OEM stuff.
A note on the pistons - they are cut by .060". Apparently that is enough to knock the compression down to the point where cold starts don't fire cleanly until the cylinders get some heat into them. Well, it will run fine at first off the glow plugs until they lose their heat and then it will start chugging and puffing smoke. It only takes until the end of my road to warm it up enough to run smooth.
Here's a cold start on my truck -
