Thumper of Orange Park GT40 heads (NOT E7TEs), these were shipped down to Thumper, work was done, and they were shipped back to Ohio. Heads flow great, but sold the car and have no need for them anymore. I am in North Canton, Ohio and am asking $450 which I think is very reasonable for these. One of the valves may need to be addressed (I can send pictures, I think it probably just needs to be cleaned but am not sure) and possibly a spark plug insert but was quoted right at $100 worst case for the work from a local machine/speed shop. Call me with any questions at (330) 361-9249, $450
