Looking to buy a used Powerstroke help!

[Twincam666]

I have been looking at used 6.0 and 6.4 PSD's

Is there one better than the other? Most i'm looking at have over 100k miles on them
how long does the 6.4 last?
at that mileage, if i tear off the EGR and related junk, do the head studs and a tuner...will it help or hurt???

I can only afford to do this once, so help will be appreciated

6.4s are the **** bro dont have to do head studds unless you plan on sick power. They are stupid strong with the right tuner aka spartan or H&S
