Glad I did not put on the intake manifolds yet! Alot of air comes out the left bank when I blow air in the air injection pipe.I turned the engine to many different positions to open different exaust valves to check the different air injection ports at 16 different ports but no air comes out of the right bank alot of air comes out of the left bank only, so no ports cloged on left side all ports cloged on right side! Odd I suspect a previous owner did the left side already so I will be pulling the right side head now.
What a shame the compression was so good at 180psi all cyl......................
