Cam suggestions for 5.9 Magnum in Canyon/Road racer?

Garrett Ellison said

Okay! In that case, Hughes magnum spring upgrade kit and specs closer to what auto x Cuda said. There are some Howard’s hydraulic roller LA cams that are available at competition enterprises that would work pretty well for you. While you have the heads off, you can have the guides machined to work with any cam you choose.
