Mike where was this motor? Basement in heat or garage? Where the rockers bolted down? Did you
oil the cylinder walls before you assemblied it? Was the motor bagged with moistier packets? I would pull the heads and check for rust rings in any of your cylinders. Spray and clean with WD-40. Re
oil. if any of your answers are no except the last. Pull the intake and re coat the lifters, and remove the inner springs on the valves. I wouldn't keep spinning that crank over. Any lube you have put on it except assembly lube is at the bottom of the bearing or in the
oil pan. Pre lube the motor and break it in. Keep the revs down, under 3500 rpm. After reinstall the springs, change oil and drive Rick Lake
