cg13 performance cams

Hi guys im new here but have had a micra for awhile now, im getting cams machined for my cg13 however we are having dramas with sorting out what shims to use the guy who is doing the cams says he can only get a 4.3mm shim and it needs to be bigger in order to work, he roughly measured them and he seems to think he can get 10.2 mm lift from the however the shims are the only thing letting us down at the moment, if someone could please share some light on how they shimmed there cams it would be muchly appreciated
Thanks alot in advance

I have some cams that are 10.2 or 10.3 lift, got them from Mickb on here. I haven't fitted them yet so I can't help with the how, maybe Mickb can help you with info.

i used a 2nd shim when i was running re-profiled cams and n/a, both under the bucket eventually
