Would you run these in your engine?

The pc seal will hold the top of the guide in place without problems

Valve discussion---after repeated rebuilds the valves were getting thin and a few ( at least one in the pic) had been replaced so it was thicker on the bottom----

I agree that the PC seal may have held the top of the guide, but the crack continues far below the seal and would have surely caused oil to get where it shouldn't. The guides also show that they were in the head when it was glassbeaded, so there could be fine glassbead with in that crack. That could manifest itself in many ways.
After I read the valve comments I went back and looked at the pics. I had seen what looked like "pitting" on the face of the valve, probably from moisture over the years...it was the thicker valve, or the least ground...makes me wonder about the ones that were thin.
