LA roller vs Magnum valvetrain...

I opened a 5.2 Magnum and compared the lifter gallery to my roller 318.

The lifters look the same and the retention spider looks identical.

Are the pushrods the same length?

Can I just swap the Magnum lifters and pushrods into the LA and get oil-through for use with Magnum heads?

Are the lifters even different?

What will the Mag heads do to that?

Aren't they 8.8:1?
