Hi guys- For some time, I have seen 4D55 parts (up to complete short blocks) from Quantico Cylinder Heads (QCH). I have seen them on eBay and on their own website. They don't offer much info in the way of national origin,and when I've messaged them from eBay they tell me different things every time: Australia, Korea, "High-Quality Aftermarket" etc.
Has anyone purchased from them, or can you offer any definite origin info?
Thanx in advance
