Well that's what I was afraid of and what I thought too. This was the last head they have and are now quoting me 2 weeks turn around to have another one machined and sent out. A few more sanity check questions: After your staff having made a customer wait a week before calling to notify them of a delay based on freeze plugs, (an issue that I'll go into another time) would you be embarrassed to send this head to them? Also, If you only had two heads left and the exact same customer had already bought one of them 3-4 weeks prior, would you already have a core at the machine shop so that you could have another unit back on your shelf? Lastly, is there anyway in hell you would charge that customer full price or expect them to pay return shipping? I understand these are possibly "loaded" questions, but I sorta feel a particular way about them and want to see where my emotions lay among the masses of this product's consumer basis. I cannot begin to explain how disappointed I am.
