If you can, look for the Toyota Engine Manual. Its a factory book and it lists all of the figures that you need. It also concentrates on the engine only, and a lot of the information is backed up by step by step pictures. It usually has a bright orange cover - unless its faded to yellow like mine has. May not feature the 1k though :dance:
Don't know any machinists in Melbourne, but I would recommend M&W engine services in Ballarat. Did a great job on my 5k a few years ago.
