Jam nut size for valve adjustment?

I'm planning on adjusting my valves soon and am going to buy the tool from Snap On (part #YA8895). Does anybody know what size the jam nut is for the Type R; I've
been searching the internet and am possibly thinking 10mm?
Thanks,
Scott

Hey, thanks for the confirmation with 10mm... time to order the snap-on tool and get the feeler gauges out along with a new valve cover gasket.
