Any aftermarket block, no matter if it's a SBF, FE, 385 series, etc., will need the full range of machine work: boring/honing with torque plates (or just honing if it comes in a rough size that's already close to finish size), square decking, and align honing.

These blocks are not final finished by any means because each and every engine builder wants to have full control of the finished product.
