Here is that "special", wonderful kit, after 3 days of reasearch, that some people weren't willing to share.
This is the kit that is a perfect fit and goes without spacers. They are GTI-6/Peugeot 2.0T ARP studs and go perfectly with the XUD.
Share this with everyone that needs special studs.
Interesting that these fit your XUD directly, as these are the studs I used, And I had to make spacers.....
You just using the single supplied ARP washer and theres enough threads left to torque down? Its possible my order ended up being MI studs, which would explain a difference, so epic if those are a direct fit for people, tempted myself as i had to mod two of mine as they were to long to clear the camchain in my 16v, could you take a photo of them installed so i can see how much headroom they need, as they might fit direct im thinking, if so ill have a set of XUD compatible studs / spacers for sale for cheap to!

Yeah thats the ones I ordered, as i figured they would be the same, but the ones I ended up getting, werent, and I had to make spacers, I thought it was weird at the time, given there near identical!

Also, looking at them, there's no way they are genuine ARP studs!? They are ARP nuts, but ARPs always have a Hex in the end to put them in the block :/
Problems with installing bolts without washers:
A. The force isn't evenly distributed across the aluminium cylinder head - you'll end up indenting the cylinder head from the force.
B. You will literally have to re-torque the bolts about 10 times as the aluminium will shuffle around since you will have tightened hardened steel against a soft aluminium head, it'll have knurled up the head and moved the ally around, through the next couple of heat cycles, you'll probably find your gasket will leak, they will require re-torquing...
C. You may as well throw what torque you did them up to out the window - again because you tightened against soft aluminium... That's why they even put in packets of ARP Ultra-Torque to lubricate between the two steel surfaces and threads when torquing down, but against aluminium, it'll "smear" the aluminium when coming up to maximum torque - causing all the metal to move, again, meaning you'll need to re-torque, but every time you re-torque, you move the ally around some more, meaning you'll never get a consistent torque setting...
Almost ALL ally cylinder head cars have washers for this reason, even just bolts going into ally stuff will have a washer generally for that precise reason... They DO need washers.

They will come with washers. All ARP studs come with washers for this reason.

But yeah looking at that picture they dont look like ARP studs to me either.

This is the kit they sent. So far no more head lifting. Will be putting some questions about the studs and why haven't they sent the Ultra-torque grease...
We put grease on them when mounting them.
I will rename the thread - WITHOUT CUSTOM MADE SPACERS.
@ruan. I said without spacers not washers. The ARP washers are mounted also.
btw. Thank you for showing the fact about the studs. I'm now upset that we paid the price for a full ARP head kit and got only half of it. They will be hearing from us.
Thank you once again.
It looks like i'm the one to blaim...
Set of 10 custom head studs with ARP nuts and washers suitable for XU10 8 and 16 valve engines. Ideal for boosted engines where head lift may be of concern.
Just because they arnt genuine ARP dosnt mean there no good, im sure they will still serve there purpose, altho id rather stick to ARP just because I know there spot on.

The studs are custom – not ARP, they are unique to us. The nuts and washers are ARP. The studs are treated in the same way but ARP are American and hence do not have many applications that suit the French market. I’m sure this is explained on our online shop description. If the studs were an off-the-shelf item at ARP everyone would be selling them and they’d be a lot cheaper.
Apologies if there was any confusion here and I hope you’re still happy with the studs…
Kind Regards,

If anyone else wants to buy this studs kit you should know this information.

maybe for future reference you should read this? http://arp-bolts.com/pages/arpultratorque.shtml
It shows pretty clearly IMO why ARP are the name to use pretty much across the board. Attention to detail!
Hopefully you'll be ok at those boost levels anyway

I'm running 2 bar boost with k16 turbo
doesn't seem much boost to be running to be lifting the head . . .
It's the amount of air a bigger turbo delivers. This is measured in Cubic Feet per Minute(CFM). A big turbo will move a lot more CFM at 15 psi than a small turbo.
