head rebuild can be as simple as strip and reassemble with new stem seals. valve re-seating and facing, or if there is damage to the head repairs as ness. generally a basic head job is around $600. $100 for the cometic HG
the rest would be the $100 per hr approx in labour to remove the head and then refit, timing belt, new oil, coolant etc
so yeh, 2k drive in drive out for a reco'd head sounds about right.
