Twice as much money and three times the time you'd planned on. And that's if everything goes well!
Lose the 160 degree stat, you don't want that.

Why, the 160 stat works great in my car?

Yes I will have it dyno tuned after, I am just concerend with parts right now. I won't be doing the work myself, so I want to have every thing when I drop it off.

Money is already budgeted, and I will come in at, or less than what I expected. I have already purchased most of the big items.

I am definately going with the 160 t-stat, almost every one uses one with this type of mod., and their cars run much cooler. It currently runs at about 198-200 WITH the fans on, I want it to be much cooler without the fans, and just use the fans if I really need them.

Don't know about this one, why would I need a tube? Crush washer? Is this a standard one that can be found any where or something specific?

There are better ways to regulate overall engine temp then with a cooler stat. All it will accomplish is to cause it to take longer for your coolant and oil to reach proper operating temperatures which increases engine wear and also hurts overall efficiency. Alter your fan-on temps if you want to cool it down but don't increase the time it takes to reach optimal temps by putting in the incorrect stat. These engines were designed to run at warmer temps for a variety of reasons. 195-205 is about the ideal for them as an average.

Coolant crossover tube runs from the back of each head then forward. The tube is real easy to damage when doing the heads...

Even if its not damaged, there are rubber crush washers between the tube and the head. This is definately a wear item that should be replaced.

I don't think the washers are "napa" items, but you should be able to get them from a dealership. Wish I had a part number for you...

this is the best i could come up with...

LT1 steam pipe behind heads (93-94) (includes bolts, seals, hose to radiator) = 10108635

Should point you in correct direction.

Your info is probably true theoretically,but just like the C5s, no one has ever proven 160 stats are bad or caused engine failure. They just work well with the proper tune. I had a 160 stat in my 96 and now in my 2000, no issues at any season. Both recommended by Cartek and ECS

Maybe I'm stupid or something but I really don't understand why a 160 degree stat will make any performance difference.

Once the stat opens, whether it's at 160 degrees, 180 degrees, or 195 degrees, it's open until the coolant temperature drops below the designed temperature of the stat (160, 180, 195, etc.) These engines don't run at temperatures under 190 or so in any case so why install something which will only delay the coolant from reaching operating temperature for a very brief period?

Surely no one here has an engine which runs at less than 190 degrees after it's warmed up, do they?

With 160 stat, my car runs ~174* on the highway.

Perhaps some bee-hive springs?

I replaced those washers with copper washers the first time I ever had my tube off. They work fine, have never shown a sign of a leak and are reusable.
Hey, if y'all want to use 160 stats, go for it. It wasn't my intent to start that old argument again.

I see headers and mufflers; what are you doing for the rest of the exhaust? Do you have emissions inspections in your part of NC? If so your going to need some cats, if the answer is no you'll probably need some welding skills or a trip to the local muffler shop for the hook up!

If you're providing all of the materials you need the following at the minimum:
thread locker (loctite)
thread sealer/sealant
anti-seize
coolant

and as an oh buy the way the right stuff to seal the china walls of your intake.
How old are your hoses?
If you're going to a good tuner you don't necessarily need the LT4 KM.

I wish I would have thought of using copper washers. I broke one (it was stuck to the old head) and decided to replace all four. VatoZone, Advance, NAPA etc did not have them so I had to special order them from a local Chevy dealer. It was more than 30 buck for the 4 washers and my build was at a stand still for two days while I waited for them to come in.
