The headers are top knotch peices. Im hoping ill be able to get my set in the coming months!

Yeah the hawks headers are very good pieces. Mine are from 2005 and are in awsome shape.

Smile Some updates, more to come

Ok, Headers are installed, master cylinder is in... brake lines are started. Fuel Lines are pretty much ran, just have to tweak em a little. Gonna try and cut the hole for the wiring tomorrow and wrap up the brake/fuel lines. I also got the top hose for the 3rd gen radiator to LS1 engine, gonna get the bottom tomorrow. picked up some spark plugs. maybe install the coil packs/starter/spark plugs.
Here are some recent pix.

it appears your fuel/brake line fittings are sitting over the header? its a known tight spot, but maybe that pic looks worse than it is.
i know mine were tight everywhere under the car, but they sure do slide in and out easy when you need them to.
looking good!

i looked and i dont.
i moved my brake line up where my fuel line used to be and i ran my fuel line up on the transmission hump a lil bit. i use braided line, and also wrapped the hell out of it. had an old starter heat shield i tubed up and then put heat tape all around it for about 2 ft. its prolly 5 pd worth of junk my car dont need, but i feel safe.

its just a lil tight on all the fuel and brake lines around the drivers side frame.

if you have a th350 or a th400, plan on cutting up the bellhousing for the headers to clear. they were built off a 6 spd car and hug a lil tight in that area. ive mesured to put a powerglide in my car, and it looks like a no go, the header collector is right in the way of the shifter linkage. the PG is just a tad wider than a th350/400 setup at the pan, making it a bugger.

Me and my buddy ended up pulling the header on the driver's side and he tweaked the fuel lines so there is more clearance.

No, it's more likely going to be a startup vid (but don't tell anyone!)...
