Having torque plates installed mimics the stresses the block would actually have with the heads bolted on, therefore making the bore that much more concentric when assembled.

The GEN III blocks distort a good bit in the upper portion on the cylinder bores with torque plates attached. I would highly recommend you use them when honing the block.

I'm up for a new block as mine was done without and now apparently has two oval bores

I'd insist on having it done with torque plates. Best to do it right the first time as others have said.
