In the process of removing the old engine gaskets from my 175, I left some small nicks in the surface. Ideally, the gaskets would be fitting between mirror-smooth surfaces, but will it hurt for there to be some very marginal imperfections? After all, aren't gaskets made out of flexible materials for this very reason? Also, if I polish them out somehow(sandpaper?) do I then need to lap the surfaces?
