I need help adjusting Marzocchi dj3 2011 I want to increase my fork length but I don’t want to change the sag or travel or rebound.

The forks are on a Rocky Mountain frame and I want the bottom of my hard tail to be parallel with the ground and not pointing down in front.
I might not understand the question correctly but I don't think you can make that fork longer. The manual for the Marzocchi Dirt Jumper 3 (click the "Tech" tab) has a lot of great information but does not indicate a way to make the fork longer.
