the heads to a reputable machine shop and have them inspect the valve seats, measure the valve edges for wear and the guides, and springs. then after acertaining what is needed buy parts and then have them grind the valves and whatever else is needed. and mill the head if it is not already too thin. straighten the head as needed. i would expect to pay from 3 to 500. for this all. including parts maybe.
