I purchased this recently from vivid and found a complete set of used heads. This is just the drivers side head and its never been installed. Its bare but never had anything even installed into it. Here is the info from vivids site

Subaru OEM Left Cylinder Head Subaru STI 04-05
Model: 11063AB120 List: $599.99

$599.99 shipped ground continental US.

Cylinder Head new left side for 2004-2005 Impreza STI 2.57 Only. Cylinder Head comes bare without valves etc.

I paid 599 from vivid but I need the money to get my car up and running. Looking for 575 shipped in the US and here is a link to a ton of pix I took.
