The only one I can find online is from euro car parts but it says it's 1.1mm thick which is too thin I think?
Got the head off the Rallye this morning and being skimmed/crack tested tomorrow and have next friday off work so want to get it back together then, I've got a fibre gasket but have decided I want to go with what peugeot intended and stick with the steel gasket!
Let me know if you have anything and can post asap!
Cheers
