I would say $500.00 for the pair . The Hi-Po 289 heads are not that much different then the 1965 to 1967 stock 289 heads . They both have the 1.78in/1.45ex valves and the 54.5cc chambers . The Hi-Po heads also have screw in studs and HD valve springs . There casting #s are #C50E-A #C5AE-E #C7ZE Also the Hi-Po castings had slotted pushrod holes . If you need to have # matching heads buy them . But if your just looking to build a 289 like a Hi-Po make the Mods to a set of stock 289 heads and port them .
