    Thanx Cancer!!
    If there are any other things I should know please respond to this thread. I work @ a dealership, Honda/ Subaru as the parts director so tools should not be an issue. But I would like to have any other things I need on hand. As rack time is @ a premium.

    Re: some questions for the guys who have done headers

    First of all, go here --> http://www.cadillacfaq.com/faq/answe...ers/index.html

    If you do Kooks, the biggest difference is the steering shaft. You have to remove a bolt and swing the shaft to the side, install the header, then rebolt the shaft together ... 1/2 minute tops. DON'T turn the steering wheel while it's disconnected. Not absolutely certain with TPIS, Katech, or the newer brands that have come out recently.

    Lastly, the above install procedure omits mention of putting the dip stick tube back in place. I personally just about crapped my pants trying to get it back it (I finally did ... get it in, that is), and others have had their cars towed to a shop to reinstall it when they were unsuccessful, so just FYI.

    Having access to a lift is a big plus. You'll do great.

    Rockauto also has MLS exhaust manifold gaskets for less than half of the price of the GM ones.

    I, unfortuantely, bought GM gaskets and found these a few days after.

    Just to reiterate Randy's pointer. If you do you will be buying an air bag clock spring. Tie the steering wheel in place or something when you have it disconnected. Not a step to be taken lightly...

    I have re-used my OEM manifold gaskets 3-4 times now with zero issues.

    Also to further the discussion on the dip stick...It really isn't that hard to get back into place but rather getting it COMPLETELY seated is the issue. Before you remove it make sure you see where it goes into the block. Then when you are done ensure the "ring" around it is seated flush or you will get a leak.

    With my B&B I had to do some light grinding on the dip stick where it bolts to the heads. I think someone else did also. Of course I think there are probably some variances on the dip stick and its bends so that might not apply to you.

    Bottom line SEE and FEEL what "good" is like before you start so you know what you need to go back to.

    Re: some questions for the guys who have done headers

    Damn, I've done headers 3 times now on Vs and it never gets easier lol. The o2 extensions work on the 04-05s but for some reason don't clip in for the 06-07s. But the 06-07s don't need them if you free up slack in the wire.
    Ive been burnt on the "don't spin the wheel with the steering shaft disconnected" bug. Its a $500 mistake.
    My 1 7/8's headers rubbed on the shaft, but nothing a few blows from a dead blow plastic hammer couldn't fix.
    I've also reused gaskets a few times and never had any leaks.
    Regarding the ARP studs, I had a pain with them too. I had to have someone hold the header from below while I hand threaded a few studs enough to hold the header up on its own.

    Thats just my .02 Cents from multiple installs/removals.

    Anywho, I have a set of barely used o2 sensors from my 05 V available for sale. PM for details.

    Re: some questions for the guys who have done headers

    I used GM OEM LS1 manifold Gaskets & these spark plug wire covers http://www.summitracing.com/parts/DEI-010502/

    no leaks & no wires melting

    I was able to untangle my 02 wires & made them reach w/out extensions
