Valve spring options

Noisey valve springs?
These guys are talking about changing valve springs when the Springs are for the cam it says and the guy hasn't mentioned anything about his lifter preload. This is a hilarious read so far...
And ****, I know springs... but I dont know everything or every spring under the sun.. and when I asked opinions on unlisted stock stuff... it was crickets. All these folks and their springs ideas were no where to be seen. Lol which i find strange...Guess it takes catalogs to connect the dots for most.
