Default Replacing timing chain vs whole assembly

When replacing the chain is it acceptable to just replace the chain alone or while its open is it worth spending the extra money and getting the whole assembly?

I was talking to some gear heads I know said to change the assembly and if I can get a roller timing chain that it will help a little. I found this one, the stock replacement assembly is i believe 120 or so this is 200 but its a double roller? http://www.shophemi.com/p-1237-chrys...by-manley.aspx anybody like what they see? He says its not liek a huge difference but lasts longer and may help gain slight power

Do the whole assembly. From what I've read the chain doesn't stretch so much as the gears wear. It's not a huge price increase.

Carefull with a double roller as sometimes they require an oil pump spacer and clearancing (grinding) of the front cover.

The double rollers do require quite a bit of modification to make them fit so unless you're running a supercharger that puts a lot of stress on your crank then you won't see any real benefit.

You can reuse the chain with no problems, what begins to go on these motors is the chain's slide tensioner. The OEM ones are crap but there's nothing better out there, so we can only replace them with OEM ones. Some people have swapped to the 6.1L slider and they've lasted through some serious punishment but they still wear out and need to be replaced. I have never heard of the gears wearing down, ever, even on the high horsepower LX builds, so I don't know where you heard that, but there is many documented cases of the slider tensioner failing.
