Theres no Chineseium in the Aussie cast iron.
Ive never really seen any issue between either blocks. Its been reported that the Chinese ones crack, the bolts are made of cheese, the heads are no good. But I cant say any of the bad quality is consistently bad.
Its more the bodge from dodgy repairers and tenants thats consistent.
But if I was to do up a motor for myself I would grab an aussie block, a later one with the bigger transfer ports.
