.. LOL! Nobody would ever accuse that engine of having a flat torque curve!
.. I am amazed that the earlier head catches up with the later head at 6200 RPMs... I would have expected the earlier head to just keep losing ground... wonder what's going on there? The less efficient earlier head must cause the engine to keep revving trying to reach its peak power for the cam used...
