I spent some money on some cylinder heads from White Performance & Machine Company, and they ended up sending me the wrong product, and no one caught it until I had to bring it to their attention, so I ended up having to change the whole deal around. I think they offered excellent service and they were able to send out the order very quickly, so I thought that was good. But I don't think that I would go back to them again after that experience. Delivering the incorrect order brought down the experience for me, despite their great service.
