I found a set of G heads on ebay.  Yes, I know there is a risk in posting this that someone will get them instead of me.... but I know very little about buying heads, and I need some help....

What questions are important to find out when buying used heads like this?  I sent him a note asking if they have been magnafluxed and checked for warps, and if they have hardened valve seats, but are there any other pertinant questions or things to look for?  If they havent been magged, how big is the risk do you suppose?  Im asking because Ive never bought heads like this before, and whether its this set or another, Im wondering what Im missing?   Anything else to look for?  also, anyone know approx weight, to estimate shipping?

Any thoughts are greatly appreciated!
