Sb magnum swap questions

Are the lifters and retainer hardware between the roller cammed LA and Magnum the same?

EDIT: I looked on Summit, they show this part number:

...to fit Magnum and Pre-Magnum roller cammed applications. If that's the case, you should only have to buy a set of those, or pirate them from a Magnum engine and drop them in. You may or may not need different length pushrods (compared to Magnums)-I can't tell you for sure. You'd also need the appropriate bolts and intake...blah blah blah...
