Alright, school me on stock roller cams....

Magnum heads had 1.6 ratio rockers.....LA's had 1.5 so the same cam in different heads would yield different valve lifts.

That's what I'm working off if regarding the pre-magnums having the 1.5 vs 1.6. For some reason I thought the 5.2 mags had 1.5 but that doesn't make sense right now.

The goal is to get the .432 cam from a 1.5 rocker engine, presumably not a 5.2 mag, and use it in a 5.9 mag with 1.6 rockers to get "almost" .460 from it.
