LQ9 head's (317 casting) can they be decked?
 

I'm looking at these heads to buy, but i'm not positive on if they are flat, if they were to be alittle warped would i be able to get them milled down enough to have them flat again without messing the heads up? i know of first gen SBC's you can mill em with no problem, i just dont know about these new heads. thanks guys!
