2.7L V6 okay after 2004

I am looking for a used car. I found a lot that has a large number of 2004, 2005 and 2006 Stratus 2.7L Flex Fuel. Is 2.7L V6 okay after 2004? Thanks.

it has a revised tensioner after that date and i believe modifications to the oil system after 2004. i would go with the newest 2.7L you can to ensure getting one with the most design changes.

Thank you for the info.
