thanks weq i think i may do this, ive seen similar buils being sold over there for around 2-4k for the head (2k being without cams and rockers which i swap over from mine) and blocks from 4-6k thats in usd so they are built by their best machine shops and builders overthere.

Tuner will most likely be James (blkcrx) as hes in melb and got similar build from what i have seen.
