Pulling Cylinder Sleeves and Replacing Them

[TomT/Williamsburg]

So I have this 39 engine with thick walled sleeves that need to be replaced. I have the original KRWilson tool kit to do this and a set of thick walled sleeves. So, here are my questions:

1 - once pulling the crank, rods and pistons, can this be done with the valve train in the block? A valve job has already been done on this engine and it has an Isky 77B installed with adjustable lifters ...
2 - tips on inserting thick walled sleeves?
3 - do I need to piston fit each piston in each sleeve once they are installed or are they already in spec?
4 - my intention is to use the old pistons and rods (after making sure they are OK), but can these thick sleeves be honed or bored for a larger piston?
5 - I know that once the sleeves are removed you can use an .083 piston and rings by Egge vs sleeves - pros and cons of doing this vs replacing the sleeves?

Many questions I know but before laying out my hard fixed income retiree bucks for whatever I might need, I would like your opinions ....

Thanks, gents ....
