Default Purpose for pinning a block?

What is the reason for pinning a block?

Does a B18C block resleeved to 84.5+ mm need to be pinned?

What about a B20Z block at 84.5mm?

For N/A it is not needed. Maybe on 86mm bore B-series..

For boost, it's a good idea. Especially if you're getting the block sleeved at the same time. Stiffens up the cylinders.
