First startup of a newly built engine

Andre, I am going to commence my engine build shortly, however this is going to go into a swap project and it will probably take about six months from the time the engine build is complete until the first time it is started up. Do you foresee any issues with this?

None at all. I'd suggest being a little more liberal with the application of oil to the bores before fitting the head and it wouldn't be a bad idea to rotate the crank a full turn every month or so.
