IF during the alingment the camber or caster needs to be adjusted, then yes cams should be installed. Any f150 made in the last ten or so years is like this. Typically your average f150 won't need the camber or caster adjusted till its aged quite a bit and suspension bushings are worn. But since your making ride hieght adjustments with the perch move the suspension geometry is being affected and needs corrected. How much correction is needed will vary from Raptor to Raptor. One Raptor may get away with no caster/camber adjustment on the second perch where as the next one will eat tires. Really you won't know till you look at the readings. When doing either perch I would just count on doing cam kits and making camber/caster adjustments. Eventually at some point if you keep your Raptor youre going to need them to make adjustments to compensate for suspension as it wears out.

As it sits now the shocks (in the front at least) limit both droop and compression. I would suspect that going to the second or third perch would put more strain on the shock at droop due to the extra preload. I dunno I'm not overly worried about mine (second perch), I figure fox wouldn't of made the adjustment available if the shock was going to fall apart.
