Of course Joe, some may have crack, at least somme small cracks between
the valves, that is why I'm are not taking any change with dammage
heads... but believe me, i always remove valves for inspection (unless
the head is finish for other reasons) but personally, i have only seen
one with a clear and visible crack out of many.

As for AMC, well, i think that we should worry about those stretching valves
