Well as long as they don't send you Ford heads LOL.. (of course Only my luck could produce that..) it shouldn't take them long to get there.. if you start a thread or something taking them apart please let me know..
I'll let you know what I find. I'm very interested in the raised port, the short turn in the exhaust, the Siamese tubes, etc. Can't wait to compare to my latest 596's that I've ported.
