Default LT Header Install

I have a set of Jet-Hot LTs on the way and have a few questions that I couldn't find answers for. I'm pretty sure that I'm going to use 1" stainless ARP header bolts. I've narrowed my gasket selection to either the Felpro 1406 or the Mr. Gasket Copperseals. Where is a good place to buy O2 extensions? I'm not sure whether 12" O2 extensions are long enough, or if I need the 24" extensions. Also, I can't remember if there is an alternator bracket that bolts to the stock manifolds. If there is, can it be bolted to the headers, or do I need some sort of spacer? Finally, does the stock oil dipstick tube still work or are there any modifications that have to be done there.

Thanks
Andrew

my LT's went on like a piece of cake. I agree with travis on the alternator bracket - I didn't use the one that goes to the header bolt... there are plenty of other bolts holding on to the alternator in my opinion. I wouldn't spend money on O2 extensions - it's very easy to splice wire in - plus you get them just the right length you want them.

use the copper seals. remove altenator starter dipstick and ANYTHING in the way. moving the A/C compressor forward helps too. Remove the steering elbow on the driver's side.
