My timing skipped one time, I had no idea what had happened. Sounded like a terrible exhaust leak, so I had the gaskets off the manifolds done. Tried to start it with just manifolds and it wouldn't start.
Maybe your exhaust is too free flowing, not enough back pressure. When my timing skipped it was only running on three cylinders and definitely noticeable. You may also be having timing issues, just not as drastic.
