6.0 Head Resurfacing?

Getting all my facts straight before I go into dealer to get head gaskets, studs, and welded EGR/upipe installed.

I have seen a few cases on here where people have gone to dealer for head studs and still are having issues, Degas bottle Puking, and some extreme cases of washing the cylinder walls from coolant and needing a new motor. What issues have people had so I know that I am going to the dealer once and only once.

What are the Head spec tolerance that I need to hear from the tech to know that they heads are as flat as they need to be so they gaskets will seal correctly with the ARP studs?

What is the technical stance on surfacing the heads to make them flat?

WE talked about this already but I wanted to just say it's a must to get them machined !! Just cause they slap a new set on does not mean they are even or true .This is what i was told by good friends and the service tech that just did my heads with A1's :} also My daughters Boyfriend got his back to day getting A1's installed ..
Hope some one else can chime in with better info !!
Give TSD a ring they will give you all the info you need as to why ...
Oh, your friend has all the info he asked for !!

I'm one of those that had puking with studs. When you get the studs demand new heads, oil cooler, and EGR cooler. If they don't give you new heads then get them magnaflux to check for warpage and cracks. I wouldn't bother with resurfacing the heads just try to get new ones.

Yeah I know you are the one that brought it up and it has me a bit of concern now. If they are not willing to let me have the heads checked by a machine shop I am going to politely ask if I can go to your guy. What are A1s? are they bolts or Studs like ARP?

Edit: I just looked them up they are H-11 tool steel, very strong, but I have read they have no give so they may eventually fail being brittle.

Yeah I have been reading some of your threads, and your outcome has me downright freaked out.

A1's are rated at 2200 and arp is rated at 1800 strength they will cost more to. From what I was told they are reusable if needed and are stonger ..

I think ARP are reusable too, they have a 180,000 yield which is 75% of tensile strength so they are rated at 220,000. Surely not quite as strong as H-11/A1 but also more forgiving...

As per Ford TSB article 06-21-10, cylinder head flatness is to be checked at all 13 spots in the illustration below. Per the TSB, flatness is to be no greater than 0.002" out-of-flat. Ford does NOT endorse resurfacing the head.

Ford does not endorse, but what is the honest Tech background for head resurfacing? and how flat the heads need to be. Are people having issues because the heads have not been measured correctly?

ARP studs are torqued to 245 ft lbs, what are the stock head bolts torqued to? and can the gaskets handle the extra torque following that spec of .002"?

How severe do cases get of head gasket failure when the cylinders get washed from coolant getting into combustion chamber?
