Engine started heating up yesterday so i changed the thermostat and flushed the radiator. My father helped me un-bow the valve cover and it tightened up much better. So hopefully I fixed that problem. The off throttle whistle is still there so next is pulling the intake/exhaust manifold...
Sweet!! Progress is good.
Make sure to talk to Joanna about putting the intake and exhaust manifolds on. It's looking like hers came out really well.
