250 pre x-flow push rods

Hi all
Does anyone know of a supply of push rods for the 250 pre x-flow motor? Am I right that the US 250 do not have the same push rods hence the ones for sale at ClassicInlines (http://classicinlines.com/products.asp?cat=39) are not suitable?

Product ID: RAS-250-ANP
Chrome Moly Push Rods (250ci)

Are there any Oz suppliers of these?

Thanks

As I understand it the US 250 does not have adjustable rockers, the Aussie does.
The US has ball ends on pushrods, Aussie has ball at cam, cup at rocker end.
So no interchangability, unless you changed rocker arms.
Have you tried Crow?

Thanks for clearing that up. I have checked with Crow and they have the hardened types that come in progressive lengths so I think there will be something there for what I want. I will have to wait to install the head and measure up what length I need. So thanks for the help.
