Extra thick head gasket for Mondeo Ecoboost?

Feck, now that's annoying - I wouldn't even have had to pay for a hair-do (not that she's bold or anything - we just don't co-habit)
Well you can still do it and then get the head skimmed a second time because the gasket face will then be convex instead of concave as it was. That way you'll end up with cams that aren't bent in their journals, valves that actually still seat on their inserts and all 4 combustion chambers the same size instead of 2 small ones at the ends and two big ones in the middle. Then it actually will have had 0.6 mm skimmed off it and you will really need a 0.6 mm thicker gasket which you don't at the moment. I'm still waiting for you to work out what gasket you do need as it stands. It's pretty basic trigonometry.

It's pretty basic trigonometry.I may give your suggestion a go (thanks for that - there's still hope!) but I've been pricing up a remanufactured complete engine today and finding the gap between that and the short block + refurbed head option not as large as I thought - I'm tempted, but I need to think about it.

PS you DON'T ever remove stresses from anything by clamping them down to something. The stress just acts as an internal spring. You can bend something straight but it'll spring back again. Even worse if you take the head out of the oven hot and bolt it to a block it'll cool while it's in a stressed (clamped) orientation and you'll lock those stresses back into it. Stress comes out with heat as the molecules rearrange and it locks back into the unstressed condition as it cools slowly. Cooling quickly is how you harden metal which in effect is locking stresses in while the molecules are semi molten and in a hard crystal arrangement. Cool slowly and it all takes place by itself. No further intervention needed.
I really should’ve known that. I hang my head in shame...
I may even put it in the oven. Tut tut.

No you've got me. I've thought about it but given what you've pointed out about the combustion chambers I can only conclude that no gasket of any size could put it right without having different compression and piston to valve clearance on the outer cylinders to the innner 2. So unless it's a trick question I'm beat.
No that's all true but there's the best compromise gasket thickness which involves working out what has actually happened to the chamber volumes, or alternatively how much has been skimmed off each part of the head. That will never be anywhere close to the maximum amount which got skimmed off just the very ends of the head.

Ok no worries I'll scrap the head. Thanks

We had a profoundly deaf Motorsport Degree student buy a modified cylinder head, build an engine and help with the rolling road session for his thesis. On the rolling road, as we improved the power and throttle response I could hear the improvements and crispness. I talked to the student about this and asked about his experience of the tuning session, he gave us a big grin and said he could 'feel' the improvements each time we gained power from a step forward!

Are you supplied with sun loungers and umbrellas, does the company ever put on parties with free beer and scantily clad male and female dancers, do you have kart racing...one mistake and your literally deep in it?
If you do reply I won't see it for a few days as my computer is shortly being disconnected
Have a good day

Thats a good one "feel the improvements", I guess his sense of feel is better than the norm due to needing and using it all the time

I used to work with two deaf chaps, they were very good at their jobs, quite possibly from having less distractions. I was once sat next to one and let rip with a huge fart, he turned to me and gave me a dirty look - he'd felt it vibrate We had a profoundly deaf Motorsport Degree student buy a modified cylinder head, build an engine and help with the rolling road session for his thesis.

I tried to keep conversation to the minimum.

Although in a similarly remote job many years ago (the Navy) we did used to play volleyball on the ship's helicopter deck.
Unfortunately/fortunately all of the answers to your other questions are a no!
