Thanks mate, where abouts are you located? Im going to use the round port head due to budget and accesability of them, i might go a downdraught carb ( 38/38 DGAS or 32/36 DGV) What are your thoughts on that? I am currently in the process or machining spacers to replace the rocker shaft springs to reduce friction, also shaping rocker arms. I mean brands and sizes, machine shops(im on the gold coast), people to talk to, build tips... Anything really for me to get a better understanding of how the process works(order of machining and painting) Literally aaaaanything you can throw at me :) Zak.
