As you know, I spoke with CE about it. I've done some business with a small shop that is next door to Arizona Transaxle Exchange. It's just a two man operation. The owner is Steve Holingston or Holingsworth or something like that. He has been into VWs for forty years and everyone in the Southwest knows who he is. CE refers some of their machine work to him. It turns out that when Cory needed his rods resized, CE sent them to Steve. I only learned that recently when talking to Steve. Anyway, Steve has done a lot of R&R with Total Seal and really knows his stuff.
One of the things Steve recommends is spotfacing the bolt holes around the case and using thicker washers which allows you to torque the nuts and bolts a litter more than usual, resulting in better sealing and almost the same benefit as shuffle pinning. He also recommends notching the lifters and bores for better oiling. I asked him about the Hover mods and he said he knows about them but then tried to explain why he didn't do them. Unfortunately, I didn't really understand what he was saying, even though he was using a partially assembled case as a visual aid. It was way over my head and I certainly wasn't going to try and talk him into doing something he didn't recommend.
CE sold me the pistons and cylinders but it was Steve who asked me if they had been checked for clearance (how well they fit together), not to mention balanced. I'm not trying to pit one shop against the other, when in fact they actually work together on some things. The things Steve recommended sounded logical and weren't very expensive so I asked him to do it for me. That's two well know local shops who were not doing the Hover mods, or recommending them. I'm done at that point.
