I have been using the software to calculate which buckets should go where with my new kent cams. I only need to replace 2 but one of them is a 3.312mm which is not on an list of cosworth or burton. All they have near it is 302 or 322. Would either be ok or shall I pick the biggest?

A 3.302mm Bucket would give you 10 microns more tappet clearance no?

Personally I would rather be 10 microns larger than tighter, so that would be the shim I would choose.
