I have a non-EGR, wide spaced intake port head with dual valve springs. On disassembly I noticed the inner springs were "stuck" into the outer springs. I can't press the inner spring out of the outer spring by firm finger force. That doesn't seem right. Shouldn't they be clearanced from one another and easily separable? They are wound in different directions, one clockwise and the other counter-clockwise (anti-clockwise?), which makes sense. The inner spring is shorter in its free state.
According to a service manual I have, the difference between the OD of the inner spring and the ID of the outer spring should be .065". That should make the springs fall apart.
Is it possible someone put a set of incorrect springs in this head or are they normally this way? The head has definitely been worked on in the past with some porting and polishing evident.
Thanks,
Gregg
