Not bad. Not sure about the no gasket though, I would think it'll be ok though.
As long as you dont hear screaching and the engine still rotates freely w/ the wooshes, you'll probably be ok.
Good thing is rotaries will run pretty much on any setup - bad build or good. Its the first rebuild, if it makes it 15K miles vs 100K miles, what matters is you built it and you've learned a new skill
