I have the dreaded loss of power in the #3 cylinder on my 2008 base Cooper. With about 115k on it I’m thinking a fully refurbished head would be the most efficient way to go as opposed to watching the valves fail independently over time. However locating a refurbished head (complete with valves and cam) has come up empty locally. Anyone know of a shop that I could contact to teach down a fully refurbished complete head for the base engine
