No. But, try using levels to adjust the pencil lines and unsharp mask for removing any softening that happened from scanning. I would scan them as color as you will have more feature available in Photoshop that way.
You can also try duplicating the layer that the pencil drawing is on and changing the top layer (pencil drawing) to something like darken or multiply.
If you need to whiten the background (assuming they were done on white paper) you the highlight eye dropper in levels to push it to white or you can use the burn too with a large brush size and it set to highlights to push it to white without too much happening to the dark pencil lines. I would make sure and push them to as dark a black as possible before using the burn tool however.

Does anyone know of a Photoshop book dedicated to working with scans of hand drawings?
Thanks,
