The main bore of a 400 is 2.841" and the main bore of a 350 is 2.641". That means these spacers are .100" thick on each side to provide the .200" smaller ID bore size.

Do these spacers take place of original 350 bearings or do I use the spacers with 350 bearings?

These bearing spacers are best described as a shim. They will shim down the OD of the mains in a 400 block so that normal 350 bearings and 350 journal size crankshaft can be used.
