Cannot convert 'UnityEngine.Object' to 'UnityEngine.Font'

I can usually resolved these kind of type conversion issues on my own, but I'm having a hard time figuring this one out.

I'm trying to assign a font at runtime to my GUIText.font, using Resources.Load (for the first time). My font is in "Resources/Fonts" and is called "Arial Black". Here's my current code below:

GameObject countDownGO = new GameObject("CountDownTimer");
countDownGO.transform.parent = GameObject.Find("HUD").transform;
GUIText countText = countDownGO.AddComponent<GUIText>();
countText.text = timer.ToString();
countText.font = Resources.Load("Fonts", typeof(Font));

The "countText.font = Resources.Load("Fonts", typeof(Font));" line above asserts with "Cannot implicitly convert 'UnityEngine.Object' to 'UnityEngine.Font', An explicit conversion exists (are you missing a cast?)"

I have tried the following with no luck:

countText.font = Resources.Load("Fonts", typeof(Font) as Font);

If someone could show me what I'm doing wrong it would be awesome :)

Also, is this the best way to assign a font at runtime?

Thanks for your time!
