Correct me if I am wrong, but those are the cylinder cooling jackets.
Yes those pockets are for cooling and as far as the wash...I would say you are correct with your diagnosis as well. is does not appear to be too bad but better to have caught it now.

Well there are no receiving holes in the jugs or transfer holes in the base gasket, so that's why I asked.

wash looks good, it is a tad rich on the mag but if your running the stock head leave it alone as the mag is the cylinder that runs the hottest due to water circulation, also the center and mag have higher compression then the pto cylinder does. About 95% of all vipers will blow up the center and the mag cylinders because of the compression and the timing in the cdi box. leave it it will live a long life there at those settings.

No it's modded out. CPR pipes, MT perf head w/customer domes, 38mm XCR carbs. Variflow. I think I'm going to bump my mains up one of two jet sizes and raise my PTO and Center needles a washer so I can use the variflow more.
