A good pipe will usually work pretty good on many engines funny enough.
I don't think I've seen any engines without squish band though. You need to figure out what you intend to do with the engine, if it's still for a 1/8 buggy racing in current regulations, or not. If it's just maximizing engine efficiency in a two stroke there are a lot of ideas out there, but if you intend to use if for current application you wont get an effective package that way.
Indeed, the 2058 pops to mind as it has worked well on sirios and nr I have,even SH engines.
Very well put, at this point we need to know what compromises have to be made and still follow rules. If the pipe is good enough maybe even go racing with it just to see how it stacks up. Then baby steps to improve the package.
I think the OS 12 and 28 have less squish bands than 21 engines, at least from the pics. Still trying to spot a pattern.
