Baudett, you need to find a machine shop that specializes in Porsches. There was no one in the state of Oklahoma where I live that was capable of rebuilding my heads. Fortunately I was only a 4 or 5 hour drive from Ed Mayo’s shop in Texas so I took them there. Many here in the US are sending their engines across the country to have them properly machined. Surly you can find a specialist in Europe to send yours to. You have already spent enough money with the idiots who didn’t know what they were doing to cover shipping charges. I understand shipping is very high right now, but so is having to purchase a new engine. Good luck.
