Cylinder head port&polish in Europe?

Hey guys, greetings from Russia! I'm planning to visit the Nurburgring during the summer and I'm wondering is there any good companies around Germany that can prepare my head? I heard head flow can be improved a lot on our N54 and I would like to rebuild and do some porting...any help would be greatly appreciated!

Cylinder head P&P can be a waste of money unless done properly and then it's a poor return on the investment. A proper P&P on an N54 head will cost $5,000+. Anything less is likely to be a hack job that will reduce power and airflow velocity.

Even increasing intake valves can be beneficial for the n54 so I don't think 5 grands is the starting point but for sure it will be expensive job and I'm ready for it..I've seen one company here offering p&p heads but they are in the States and they need a core so I'm trying to find someone a little bit closer to my location ;-)
