It's pretty easy to change the bearings, but you do need to have the necessary special tool to allow you to draw them out. And all 5 are different sizes!
You can download a sketch of the special tool here:

If you have a friendly machinist, he can knock one up.
Just be careful to draw them squarely into the block.

I always do it as a matter of course. And just ensure the oilways line up.

Not sure if it's on the drawing or not, but mine are all tapped M10 and I use a long piece of studding to draw the bearings into place.

You can get various tools

One of many videos

I would NOT try and install bearings without some sort of alignment tool too. And a tool to draw the bearings into place with threaded rod would give you more control....although I would aim more for like M16-20mm threaded rod, than M10.

I tried M12 on my LS a few years back and it didnt stand a chance. Far too small.

Although I did recently use one of the hammer tools as per the video and it was very easy and effective.
