    Chirping noises usually indicate a vacuum leak....check the hose from the intake manifold port to the petcock, and the three other rubber "caps" on the other three intake manifold ports.

    Also check the torque on the headers nuts.

    How do your carb manifolds look? Are they cracked from dry rot?
