Chevy heads.....$$.....???

My Father in-law has a pair of 1973 or 74 350 Chevy heads. He's looking to sell them. DON'T QUOTE ME ON THE SPECS. I think they're 2.02 and 1.90. What could he get for them?? THANKS

if they're cast iron he might get like 100 for them, a little more if they're alluminum... odds are if they're that old they're prolly cast iron, it also depends on what kind of condition they're in and whether or not he's selling bare heads or if he's including valves, valve springs and retianers...

if there the 2.02 1.60s there decent stock heads because they have the bigger valves..
