360, LA360, or Magnum 360?

Idk the down side except they cost more lol I'm new to rollers and the comparison i made above is wrong lol found this short bit on why they say to go roller. Roller*lifters can be re-used over and over again. The ramp speed is lightning fast compared to a flat tappet cam, and the lobe profile is awesome which only equates to making more power. You get a better idle, more manifold vacuum and better throttle response with roller cams.
