Is the rail on the Mancini waterneck as thin as it looks in the photo? My chrome Moroso is already warped and leaking.

I was also told that Napa sells a stock waterneck for $6 that seals well. And 440source has a chrome one with a super thick 1/2" base.

On my W-2 intake I had a issue.. there wasnt a shelve in the hole to set the thermostat on and the goose neck didnt have it either... I ended up welding a lip inside the hole and ground it for the thickness... I also used a larger stat and ground the OD down to just fit the hole... works fine now but what a PITA... I use a billet chevy housing since they are the same but this one has the O-ring and turnable hose fitting

After struggling with trying to seal a gasket style housing I bought a Billet Specialties (90820) housing with the o-ring. I bolted it on with no sealer, just using the o-ring. It's been off and on several times and hasn't leaked in 6 years of use. I bought another one for a new build and did the same, no sealer and no leaks. It's worth the extra money. That's good to know, I was looking at that one at Summit today.

Is it a good billet aluminum that won't warp? Looks like a nice piece if they're still available.

I'm gonna have to order the Mancini waterneck, I looked at the $6 one at Napa yesterday, looks like a nice quality piece but it doesn't have the widened area at the top of the snout to help hold the hose on, seems like it'd be easy for the hose to slip off.

Same pattern as Chevy but Mopars have a recess in the flange for a t-stat. Chevy the recess is in the intake.

That's good to know. I thought the recess was a different size, requiring a chevy thermostat. Didn't know the recess was in the intake. I had my heart set on that $17 billet piece!
I like the $28 billet 440source waterneck and their $15 chrome one with the 1/2" thick base, I just didn't want to have to order it and wait for it. Shipping is $9.99 for each. It sucks to be on a tight budget and a tight time schedule.

It says they're solid aluminum, does that mean it's billet or not? I'm about to buy the $17 billet Chevy piece from Summit and just not run a thermostat lol. I've never even ran a thermostat in my previous cars but they had electric water pumps.
