60lb spring talk
I have read and read and cannot come to a conclusion. Do you need 60lb intake valves? Is it actually necessary unless your running a high amount of boost? And if so at what boost level do they become necessary?
Kinda just starting a little discussion on this and see what comes out of it.
Also from my point of view this is just a dd street driven truck with nothing more than some street flogging.

unless you are doing 5,000 rpms, you do not need these on the intake side, 60lbs springs is not a from the high horsepower side, it comes from the Heavy duty industrial side, the exhaust side has the 60lbs springs becasue they go into machines like dozers, back hoes, skidsteers, etc; they also used them in the freight trucks that have exhaust brakes on them.
I have a skidsteer and it turns over 3800 rpm and the intake springs are still the 30lb stock and the exhaust are the 60lbs stock springs from cummins, have not floated a valve yet, going on 3100 hrs.
but with all that said,on my truck, I even put 60lbs springs on my intake as well, just as mechanicl diesel said "peace of mind"
