Get it completely dry and take a compressed air gun and give it a shot of air into the fuel line with the cap on. If it were even dented, this was enough to pop mine back out when I ran over a curb at night and put a pretty good dent into the fuel tank. Also what your looking for is just a machine shop to bore your cylinders out to the next size. It doesn't take a specialist to put it back together. Any cylinder head shop can do a .090 cut on the head and that doesnt even take special pushrods. 3 angle valve job, reground cam, 2bbl intake... headers. That's about as far as you can go with a slant. Taller gear in the back is the first thing I would do to wake up a slant, most came with cruiser 2.76 rears.
