Yes, it should turnover. You should have "S" curves in the leader which will provide slack. But not the whole leader piled up at the end of the line.

The Harvey leader directions that I recall included tying a longer tippet, test casting, and then reducing the tippet length as needed to turnover with nice S curves. This, of course, depends on fly size / air resistance, line, casting style, etc.

I think one of the great benefits of tying your own leaders is that you learn more about leader design and can make adjustments to suite your style.
