These heads are low performance originally used for low speed RPM and torque, probably a truck motor application. Not really desirable.

If U can get a $100 for them sell them. Nobody would be interested in them unless they have a mark5 motor and dont have heads or have a cracked one and dont relize there are several other heads they could use which would be a big improvement in performance.
