Cylinder Head rebuild, Whats involved and how big a job?

[ukvolvo]

I am thinking of taking the car off the road a few weeks and doing the whole head in one go as she uses oil (valve stem i would guess) and a little water.


Just how big a job is it? My old man is up for helping me out but im still curious if its a monumental job? Does the diesel pump stay attached or is it everything off?

I am questioning my sanity attempting this and need reassurance

Thanks
Mick
