Thats very typical. Many combos are figured for 10.720 as to allow for a -.005 clean up cut off the decks to provide a square , clean deck surface as most old blocks need it, and to be honest, most new blocks deck surface finish is pretty poor. If you need to use Cometics or any other MLS gasket, that .005 will give you enough room to correct the RA for proper finish.
