I have a spare 3.4 cylinder head which I am considering trying to recondition.
The valve guides are worn, and I will have to eventually take the head in to a machine shop to have the valve guides replaced, or more likely to have the guides lined with, I think, K- liners.
My question is: do the studs which hold the camshafts in place have to be first removed from the head, so that the valve guides can then be worked on?
I got the cams out, but these studs are stuck. The cam studs are not bent or mangled, the exposed threads look good.
So, if it is even possible to have the head fixtured, and machined, with the cam studs still in place?
It would save a lot of effort if I didn’t have to try removing the cam studs.
Thanks in advance for any help.
