Here is what we do with used FE heads. Dis-assemble the heads completely then bake, tumble, crack check and tap all holes if everything checks out well. The heads will need bronze guide liners or bronze guides. Hardened exhaust seats installed, new valve job done, deck of heads surfaced along with the exhaust side that will probably be warped. You will need new valves, springs and seals at least and more than likely locks. You might be able to use the retainers depending on the springs that you use. If you use a dual spring you will have to machined the heads for dual springs and a positive stop seal. This is what pretty much has to be done to any used heads to bring them up to a decent head. This will normally run about the cost of the new Edelbrock heads if they are done right. This why we sell very few original heads any more except when required by the rules or a restoration. If they are not done right you will have them back of in about 2000 to 5000 miles fixing them because of worn out guides or the exhaust valve sunk into the heads. Good luck, Keith
