If you are sure about that stroke, then you need to compensate to get the timing back up. Seems quite short though. 59.8 is about the shortest usually seen.
Based on 59.67 stroke and keeping 125 as the traget for the transfers. PBT should be 0.40mm under or as near as 2.0mm packer gets it. Exhaust up to 33.20mm will make quite an exciting ride.
