Roller LA cam into Magnum?

I thought the difference in cams was between p-car cams out of roller LAs rather than 5.2 vs 5.9 mag. At least I think that’s what Ken @ Oregon Cams was explaining to me.
Yes, that's what I said. The 318 roller was slightly hotter than the 360 roller, and translates into a mild upgrade when installed in a Magnum.
