That can't be right otherwise we would never be able to do the head gasket?
Would it just "wear in"?

Have you actually checked to see if they are warped?
Hmmm
Are all 4 the same then? Warped in the same place?
What is the history of the heads?
Is the block straight?
A cylinder head specialist should be able to sort it either way, being aluminium it should be possible.

Have you tried torqueing one down on a block and then trying the cams in it then, funny how all four are the same..??

I've got to to rip the head off Gul's engine shortly, that one was well cooked and acting as a water pump, so I am expecting in to have warped it's head, so it will be interesting if I have the same issues., whilst it's in bit's I may well forge the bottom end and shim the block from added security, not that many people crack 2.3 liners, but better safe than sorry whilst I'm in there, future proofing I think they call it, as she is always receiving olives cast of upgrades...

It's odd that on the one that the inlet is stuck on, you'd imagine both to stick if the warped head theory has anything to do with it.
As for garage time, to cold for me and I have to sort the place out fully before starting or continuing any project at present

Are they completely dry ie no lubrication? If so could it be as simple as a gum type residue binding things up?
Just trying to go back to the start to find root cause. Not trying to insult or upset.
Sorry re-read from the start of the problem.
So at what point of tightening the covers do they lock up?
Might be worth doing a progressive tighten to see where it happens. Is the cam then hitting the cover? Or is the tightening causing an unwanted load somewhere?

I cleaned the points of contact before installing the the cams, putting a small amount of fresh oil on the contact points, so they are not dry
and all seems well. place the cam cover on and push it down, then some cams become tight.
I say some, as we are talking 4 different heads.
Tighten up the bolts only seems make things worse
are the cams hitting the cover? what makes you say that?
that had crossed my mind, why they would I don't know, but interested in your thoughts
I know there is a specific way to torque the head bolts, is there one for the cam cover?
