heads

I know this has been discussed in a few head replacement threads but not in too much depth

I understand the heads get cracked and some have seats replaced etc

What is everyone doing for any performance or preventative measures with the heads when replacing or machining?

What kind of cost is involved?

When I had my heads checked, I ended up need new valve seats. I paid $800 and the machine shop machined the heads flat,(both were off less than .004) magnafluxed, installed 16 hardened exhaust seats installed, 16 intake valve guides, 32 new valves were installed and lapped to the heads. They told me I didn't have to get new intake valves but I figured it was only $80 more they were already doing cylinder head work... so I figured why not.

Wow... I was quoted $1600 dollars for the same work. I would have done it for $800

The guy that did my machine work is a friend of a friend, but I don't think he gave me a deal... But who knows. Maybe he did!

I would say if you can get the heads cleaned, magnafluxed, machined flat, new valves, guides, and 32 hardened seats installed for $1600, I wouldn't say that is too far off. That is what mine cost (of course I also had larger 6.4 exhaust valves installed too as opposed to 6.0 valves (1.5mm difference)). Then for another $500 I installed RCD's upgraded valve springs.

I just got mine done also. Took off 6 thousandths and fluxed them and pressure test. Also did seats and new guides. They also lapped the valves for proper clearances. Cost me $975.

MustangMike, read the machining the 6.0 thread at the top of the General 6.0 forum. It will answer any questions you have about proper prep of the 6.0 heads. Well worth the read.

I have read what seems to be every worth while thread on 6.0 heads. But just like this, I've seen prices range from 800-2000 for all the seats, milling, magnafluxing and valve inspection. If I am gonna pull the heads i think I'd rather have all of the seats done. Has anyone had problems with the area around the seats after machining and installing hardened seats?

No problems here... Cheap insurance to have hardened seats installed(especially on the exhaust side)

No problems here either. Adrian also has (roughly) the same heads as I do and his have had WAY more abuse on them too and they are still holding up good.
