Highly recommended!!

I would and have. By not doing it the chances you will float a valve is highly likely.

if you dont rev past 4k you dont neccesarily need um, say if you wanted to wait to the pull the valves or moneys tight just keep an eye on the skinny pedal and dont go past 4k and you'll be alright:thumbsup:

Whats your guys stock spring rating? I'm pretty sure the 24v are 50-60lbs, are they the same spring? Can you guys just buy 24vs stock springs as an upgrade?

I thought the valve could start to float at 3200-3500???

On that note I have the 4k in mine and have not done the valve springs but even If I had the springs I would never rev it over 3000 in my opinoin 4k is just to high to be reving a cummins that I want to last. The only time mine gets over 3000 is when the tires break lose then its 3200-3500

^^ thats true it shouldnt be reved that close to 4k, but you get the picture if you dont go over a certain rpm even with the kit in, you would be ok, but regardless get them done eventually

puredieselpower.com has a set with titanium keepers and retainers and you get 30 bucks off the valves if you buy em together. thats what i was gonna get.
