these heads actually made in australia?

I got mine bare off evilbay right about when they hit the market. I took a chance when everybody was shying away from em. Payed $200 each, think i got a good deal. I think they are up to $400-$450 each bare. I shoulda bought a pallet of em back then. I would never buy a set loaded w springs and valves. I was told the guides in em are junk. Expect to change those out.
