Who should I contact to get a quote for having a crankcase machined out to 92mm and heads to 94mm barrels?

Anyone have an idea of what this kind of work will cost me?

Have many people over here in australia machined down their 94mm barrels to fit a 92mm case to retain some of that case strength in their performance 1916 or larger engines?

Its quite a common practice for performance build ups in the US now, especially on forced induction.
