High port to low port swap, wiring harness?

Based on what I read - and my extremely limited technical knowledge - this
is what the answer seems to be....

Swap should work
Some sensors may need to be swapped over if the sensor connectors don't
match (i.e. water temp)
Throttle cable may need some work/"engineering"
Looks like swapping HP cams into LP engine is a good thing.
May have some extra wire on a couple of sensors

Anyone of you smart folks have anything to add?
