[dlv4540]

I have a couple sets of 3873858 heads for sale. First set is bare and dated I-13-5 and I-14-5 stock with no porting but one head has been milled and the other has not been touched $1650. Second set is a complete set that was rebuilt but I don't know the exact mileage on the set. This set is in excellent orignal condition with no milling or porting and has the stock size 2.19 intake and 1.72 exhaust valves dated D-18-6 and E-2-6 $2500. Third set is a rebuilt set that has some porting on the exhaust side and has been milled. The set has stainless valves with 1.88 instead of the factory 1.72 and had a valve job with a new set of springs installed $2000. 330-770-2517
