Pi Swap Kit Question

What does "good used heads" mean? I would not put unknown heads on without having them checked/rebuilt due to the cost and time to R/R if they are found wanting after install. For that price I would expect reconditioned heads, but that is me I guess.
Found this on another Forum:

oh yeah and a 3/8 NPT tap for the extra coolant sensor.

While MPS auto salvage is a good and reputable place that you can catch some good deals on, that price was kind of high IMHO.
