My home inspection of Speedmaster heads

Now, I;m no guru and I am not there standing next to your heads, BUT, it looked to ME like there was too much slop in the guides. Hard to tell, because I think there was some movement of the whole head, but I'm not certain. If there was not, I know I was seeing at least .005" movement. That's too much.

That SAID, I would rather them be a "little" loose.

But again, I'm not there, so that call is hard to make. They look like good castings, though.
Maybe a little knurling would help the oiling...
