Neither - right on should always be the goal.
From what I understand, too tight prematurely wears the head (valve seats) and too loose can have a similar impact on the valve train due to the valves "slapping". I do my best to get them right on but usually err on the loose side.
I know that if the intakes are tight it can encourage backfire and blown carb boots. The intake valves are still open a touch at point of combustion causing "backfire" into the carb.
I adjust mine quite often and it seems the intakes are always snug and the exhaust remain adjusted.

It's not unusual to have to let the intakes way out, especially if this is the first time you have adjusted them in a while. All water cooled engines tend to have their intake valves tighten over time but the raptor magnifies this "event". Keep a close eye on your valves.

3-4 turns is way too much sounds like to me, are you sure you have the piston at the top dead center position?? Did you follow the manuals instructions??

It's pretty quick once ya do it a couple times. At first it'll feel like a pain to remove the plastic and tank but it's not bad - well worth it. Moving at a normal pace I can do it in about 1/2 hour (or two beers). It's a good excuse to poke around in there where ya normally cant see to make sure other stuff is OK like wiring, carb boots, etc.....
I check mine whenever I have the tank off or about every 300 miles or before any high revving trips like a race or big dune trip.
