383 power upgrade help

The heads need guides, exh seats were going away they were so bad.
Springs were in at 1.883 130-135 seat and 250ish @.500

How much less to recondition them compared to a set of $1400(plus shipping and a tax) Stealths?

At my shop the price would likely be pretty close…….depending on exactly how bad the oe heads are.
