The Continentals are built significantly different from the VWs. The bottom oil seal for the cylinder fits between the cylinder base and a chamfer in the case. I suppose I could shim it some if I wanted to invest the time and effort into building the shims, but there are other things that aren't going to fit properly if I start shimming the cylinders. Without doing something significantly different for a seal, it would likely be a real oil leaker. If I was really serious about building a high compression barn burner of an engine, I would buy the 10:1 pistons from Light Speed and buy new cylinders to run them in. Since I'm not interested in making that kind of investment right now, and reliability is more important to me than HP, I've converted my engine back to stock and will see how it does. Hopefully, the better breathing exhaust will make up for the HP lost to converting the engine back to stock. I always figured the higher compression pistons were worth 5 - 7 HP. Some testing is definitely in order once I get the plane back into the air, hopefully next weekend.
