GT40p and lunati 51025

75 is a good price for a set of JY heads. I would just check the mileage on the car, and check the condition of the car of course. If the motor is already all torn apart and you can tell has been sitting in the rain for a while I'd be hesitant. Also make sure its not a cash for clunkers car. As far as the springs and cam goes I cant give you any advice. The TFS cam's are always a good option but thats what everyone uses. If the car still has the intake on it I would take the intake as well. I mean you could also use the stock intake...you didnt really give any price ranges or what your goals are.
