I have bought from them three times. I've got their heads, oil pan, distributor drive shaft, and a good assortment of other things I can't think of so far. They have been great. All parts have been as advertised and their customer service has been A+. With me being in Canada, they've always shipped things out by the means that I want, so I can only say good things about them and their products. I would not hesitate to run their stroker kits in my car if I had the coin.
