So this is just me but i agree with the thread and always replace lifters with the camshaft solely because they wear out together. Addressing the elephant in the room here - cost!!
it is expesive, no way around it.
I did my 2012 1500 ram with a 2016 dodge charger 392 cam and non mds lifters with a tuner that only turned off the mds. there are many of them out there that will do the job. that said i removed the mds solenoids and installed plugs in there place. this is "A" preferred method.
You can still run MDS just replace the lifters with the same newer lifters.
Chrystler has gotten a lot of heat for this but basically comes down to proper maintenance.
In Short do it right the 1st time!!!
If you use the 392(6.4L) cam it is actually cheaper than the 345(5.7L) cam off of rockauto.com. Then again you can always go with aftermarket cams. again its costly. looking at the power graphs though most of the aftermarket cams dont see any gains until you run 4000 rpm or more and the 392 is a more aggressive cam on bottom end so thats the way i went.
I did the work all by myself and outside of the oil and fluids, the parts were roughly 600 dollars. thats cam, lifters, and gaskets (rockauto.com).
Hope this helps.
