The PO of my 350 has one of those cheapie chrome water necks installed, and the O ring in it is now leaking. I just want to be done with the whole thing and get a good, reliable one.

Anyone have a recommendation? I'm not overly worried about cost, but I AM worried about coolant leakage!!
 
Get a cast iron Dorman and be done with your issue...Regret I am forgetting the part number right now.
 
I'd be interested in the part number for the cast iron straight one as well. I don't really want to put my crusty 1955 one on my new manifold but I certainly don't want the chrome o-ring one either.

Here it is...P/N 902-2017: Dorman Products - Search Results

I've recently bought a couple of them...No leaks...Good product

I probably looked at 50 diff ones so I may have had the wrong store. Here's one of the $30 MG ones (albeit for an LS motor):

That one is nothing like the original that you ended up ordering...Chrome and a swivel.

No matter now though...You've got one on the way.

Yes, I realize that one was diff- I was merely stating that the prices for the other ones that I was reviewing weren't too far off price-wise from the NOS one that I bought, so I did not feel that I got hit too badly for the price. Since it's cast iron, though, I'll have to figure out what color to paint it, as it's going to be sitting on top of an aluminum intake.

i am sort of living this little dream as well. i could never get the original neck with the oring to seal right. one thing i did notice on it was that i guess it had been torqued down a little too much that the ears were basically bent down, meaning, it was never going to sit flat. i ran it over some sand paper for a while to flatten it out. that worked pretty well, i also put the gm gasket with the little rubber oring, and that sealed stuff up. i just changed thermostats, i guess the gasket wasnt quite as reusable as advertised, it leaked, so i switched to the Mr. Gasket neck i had bought earlier, The oring was bundled up inside, so it wouldnt sit right unless i used a little silicone to help it. The Mr Gasket one is way lighter than my other. its on the car now, leaks a little, but im afraid being 80 miles from home to torque it down a little more for fear of snapping or bending it.
 
I always wonder why GM put the water neck mounting just a little crooked? And that after all these years no one made a water neck that makes it perfectly straight. And why do all the aftermarket manufactures of intakes follow along and give them a slight angle? Not a big deal, my straight hose bends a little, just makes me wonder?
