My suspicion is that maybe an oil way has somehow got blocked and caused oil starvation, that's my current thinking.
Block was stripped and long studded earlier in the year then rebuilt.
Oil surge can be ruled out then as can oil pump failure, it really only leaves oil contamination blocking an oil way as you have said. It must be frustrating for you as there wasnt anything obvious that caused it.
Are you doing the rebuild yourself or getting it done by one of the Cosworth specialists?
