cost to rebuild cyl head stock

400??? seats are 18 a piece, guides should be a part of the rebuild, and valves are about 8 a piece. My guy gets 75 a pop for V8 heads....And that includes bronze guides and Serdi 3-cut valves. I think he charges 125 for a 6. Get a new head off Ebay. here is a hydraulic lifter head with hardened exhaust seats...http://www.ebay.com/itm/CHRYSLER-PL...es&hash=item56335f9091&vxp=mtr#ht_2133wt_1272
