360 magnum block with LA parts

So I previously had a hydraulic flat tappet 360 La block with a mopar purple cam (which i want to re use) now I have a 89 360 La roller cam block I was hoping to use that same cam with trick flow heads and 1.6 ratio Mancini rockers just wanted to know if I would have to get special pushrods/ lifters to go with that
Any/all help will be greatly appreciated
