I managed to get my hands on a 12g295 and a set of twin carbs for decent money from the bay, i refurbed the carbs and sold them on, so the head cost me about £50 in the end.
The plan was to use it and a HIF38 on the otherwise standard engine (stage 1 counts as standard if we are honest). It was rusty when I got it, so i stripped it down and took it to my local machine shop. They inspected it and told me it needed new Valves, valve seats, guides and a skim...expensive, but I thought it would be a money well spent.
New Valves...

Shiny new guides

Chamber 1 - looking good sa far
