Pinning?

Hi, its me again, I saw a website about pinning your sleeves. If you don't knw what it is, its where you drill holes int he side of your block and put set screws in so they are right up next to the cylinder wall, this is supposed to keep the walls from moving/breaking. Does anyone have a comment on whether this works or not. Im am going to have my motor out for the piston/rod upgrade, and im just trying to find anything cheap I can do while its out to help me out later.

Thx,
