I've never been a fan of the cheapie chrome ones. I have not tried one of the "o" ring types, maybe someone can chime in here! I've had good luck with the stock-cast!!!

I've got an original one on my performer manifold works great and looks awesome painted gold.

I know it and i´m sure it seals perfect...but $ uff!

Original is the cast one?

For what it's worth, the aluminum ones are cast, too.

I think that the main reason the factory switched from aluminum to iron was to switch to the bent tube with straight hose instead of the pre-formed J-hose. But it's generally accepted that the iron housing seal better, too. Then again, an iron housing might suffer galvanic corrosion with a Performer manifold.

Regardless of which housing you use, make sure the two sealing surfaces are flat.

I threw away the chrome piece of junk that came with the car. I cleaned up the original and stripped it bare. I used a parts store gasket and a little gasket sealer. It hasn’t leaked for about 8 years so far.

I've dealt with a lot of chrome thermostat housing whether they made from Taiwan or other countries, they always leak. No matter how much silicone i use or double gasket, etc...they've always leak. So now i switch to a cast iron type and it hasnt leaked yet.

I have a cheap Taiwan chrome jobbie that don't leak. But the PO put GOBBS of sealer on it. Looks pretty disgusting and will be changed soon.

Yep... 100.00 is kinda spendy... My cheapo chrome one is a leaker too... I will have to show it some love this fall...
