They are still on the car but if I have a buyer I will pull the motor and sell the heads. I think they have a 64cc combustion camber. They came on one of the original 302 GT40 create motors. If I remember correctly the part number for these heads was M-6049-X303. If want to see and hear the car run let me know. I will even throw in a e303 cam and a set of crane cam 1.7 cobra rockers. $800 for just the heads / $1000 for everything
im picking up a car tommorow car has a set of GT40 heads coming with it ...i can post up more info after i get them they are already off the car as im parting the car out ....ill get ya more info then just shot me an offer
gonna do boost and dont want to crazy of a head due to breking the block so keep power levels down around 400-450 to the tire but yeah the info on the gt40s
