I had contacted the company a few months ago. Castingings are done in china. they are machined in the U.S. The few articles if seen on heads that are made for Patriot gave good reveiws. They do have thick decks etc. They are quick and very friendly to talk to. The bad rep seems to come from factory heads they modified, that's why they started having castings made to their specs. I decided to go with a cleveland or I would have used these heads. Shoot them an e-mail before you make up your mind.
Every since the free trade agreement, you can't hardly find much that isn't made over seas. Boeing, Frieghtliner, Delta, space station, etc. Imho, I spend my money for the best bang for the buck. The arf heads are great heads, but if you aren't racing I'd rather have the 600 bucks to spend on other parts.
