2 questions on steam lines
1. Is there picture anywhere of all the different styles of steam lines?
2. The LT1 had the crossover steam line on the back of the heads. The LS engines have it on the front & the back holes plugged. Is there any advantage to having it in the back with the front plugged, or with a line coming from both?
Thanks,
Scot

Supposedly having the backs plugged can cause hot spots on the rear cylinders. I doubt it will matter unless you're making serious power.
The f-body line connects all four under the intake.
The truck connects the front two and the hose comes out up top.
The Corvette connects the fronts and the hose goes towards the front of the engine.

different angle position/intake setups are usually the reason why either the fronts/backs/all are connected.
they all look pretty much the same with the exception of the fbodies which didnt have 2 caps and 1 tube (either front or back) but had a "spider" that hit all 4 corners and had an outlet. Im not sure of a picture reference but if youve seen one of them they look the same with slightly different bends (ie, i think trucks had a deeper bend because of the intake)
ideally theyre all connected so you can release steam from each section of the head, but gm didnt think it was necessary based on the usage of the engines, the angle they sit in vehicles, etc. If youre racing id connect them all.
EDIT: also **** lt1s and their banjo bolts, i remember having a hell of a time on the back of those heads lol

They changed this setup in 2001 when they started using the LS6 intake on all LS1 f-bodies...the LS6 intake had a dropped floor compared to the LS1 intake, so there was no longer room to run the hard line under the intake. The rears on mine are capped, and only the front two are connected. I will likely look for a way to hook the rears back up, but it has to be clean, and so far, I've not been able to figure out a way to do it without making it look like a bird's nest of tubing and fittings.

definitely should not be capping all 4, that's just asking for trouble. I opted to use all 4 on my setup; ls3 tube in front, l92 in rear, semi rigged setup to connect the two for now. Will be going with something like this later to clean things up:

So looking at the link from reckless how do you install it? Does the nipple pop on or do you have to remove the piece? I looked at the back of my LS3 and there is an open threaded hole for the bolt but where the steam port is it looks like a popit

From what I have read it should go back into the system. I don't know how often it releases but I would think often and if so then just a bottle would fill up quick.

the cheapest ones i found will require adapters to get to AN, but may still be worthwhile for some:
