Brought my leaking 2.3L Ecoboost head into Zinn for repair. Robert concluded that the head had a flaw or a pinhole in the casting. We agreed he would pin the flaw and machine the surface. Upon picking the head up the finish was flawless. After reinstall by myself into our 2017 Ford Explorer the engine is running perfect. I did put in ARP studs and a Cometic head gasket to ensure a good seal just for good measure. Price was way cheaper than I expected for the work and was done in a timely manner. Mr. Zinn even carried the head out to my car when I picked it up. read more
