Is there a big difference in installing either one? I will be installing a set of lt1 LT headers soon and have a couple buddies who are willing who have setup ls1 headers, just want to make sure there is not a huge difference.

Anyone? Or should I just take it in?

the install for ls1 headers and lt1 headers are basically the same

I do not remember the reason why, but I have heard LS1 headers are a bit more involved than LT1 headers. The long tubes in my LT1 were not bad at all. I did them in my garage on stands...

Alot has to do with AIR and EGR also. If you get race version headers without those provisions, they are much easier to put in.

Well I ended up going with the one with the provisions, gotta love emissions. Well that actually answers a few things in a way.

I think the LS1 is just a little bit wider if I remember right.. it makes things to be a little bit of a pain in the ***..

The process of installing headers is basically the same with all cars. The specifics
for the LT1 are:
* disconnect negative battery cable
* remove engine temperature (gauge) sensor on driver's side.
* remove plugs
* remove old y-pipe and exhaust manifolds
* remove oil dipstick tube.
* remove starter
* remove driver side engine mount through-bolt
(* some headers require the removal of the steering shaft)
* lift engine on driver's side enough to slide header in place and install
header bolts loosely.
* drop driver side engine down and reinstall through-bolt

* remove (it should be there) single ground wire (about 18 gauge)
from passenger side engine block (so you dont snag/break it).
* remove passenger side engine mount through-bolt
* lift engine on passenger side enough to slide header in place and install
header bolts loosely.
* drop passenger side engine down and reinstall through-bolt
* reinstall single ground wire back to passenger side of block
* replace starter
* replace oil dipstick tube
* tighten all header bolts up to proper torque
* install spark plugs and wires
* reinstall engine temp (gauge) sensor on driver's side
* install y-pipe/whatever on back-side of collectors.

* if going with emissions headers, install all emissions equipment.
* re-install negative battery cable.

Hopefully, I've covered most of all the important stuff.

whats the best way to lift one side of the engine

If you have to lift one side of the engine to get the headers installed, it is probably time to change the motor mounts anyways. Just use a solid piece of wood and a jack to place under the motor. Un-bolt the motor mount bolts and go from there.
