The intake cam on the high port is an upgrade, and is an extremely
simple swap. Nothing else has to be done to compensate or make it work.
No sensors, no nothing. Just make sure you keep the mechanical timing
correct and tighten down the cam caps slowly, carefully, and only a
little bit on each cam cap at a time to make sure the cam does not snap
on you.
Here's more info on cam lifts.

And here's actual measurements and pictures I've done on a low port cam
versus a high port cam.
