There's several guys on here that represent the 3000 Series, and a few of them have been into the hydraulic system specifically - as soon as they drop in they'll be able to answer that question. Sorry, I don't have enough experience with the 3000s to be able to answer ya.
Just out of curiosity, what do you need the thread info for? Hopefully no stripped out ports!
I have a GT3200 with deck and front lift valves.
As I started thinking through on: http://www.mytractorforum.com/showthread.php?t=208104, I am going to extend the supply lines going to the deck lift up to the front and run a new set of lines from the deck lift cylinder to the front which will hook into the extended supply lines.
This way, I can use both hydraulic lift and hydraulic angle without spending an arm and a leg on the 3rd valve kit.
