I'm currently prepping the basement before framing the walls and had a question in regards to installing blocking where the walls will sit parallel to the floor joists...

Does the blocking need to be the same size as the 2X10 joists or can I use perhaps 2X4, 2X6, or 2X8? The blocking pieces will be attached to the nearest joist and to the header around the perimeter of the basement and will sit on the foundation wall

The reason I ask is that the joists that the blocking will attach to have bowed/warped slightly and it is somewhat difficult to force the 2X10 blocks into place. I thought using 2X4, 2X6, or 2X8 pieces might be easier to manuever into place than 2X10
