i think he's F'ng with you, and i'd stay away from anyone that reccommends stronger springs for a stock cammed engine, or a modified engine that hasn't experienced valve float, and/or hammered & strange wear marks from bouncing on the down side of the cam.
it needs the weakest spring possible, that will keep the follower/lifter in contact with the cam at redline + 500 to 1000 revs more for missed shifts & safety.

heavy springs = less power if they aren't necessary.
turn your cam over by hand, and then imagine the HP it takes to do that at 7000 rpm!!!

i don't know anything about turbos.
