What boost level are you running?
The Euro head has a metal diaphragm that is unforgiving of boost spikes. If this has happened your AFR's will be off and not able to stabilize. It will dump fuel in some cylinders.
The cause must be determined before another head is possibly damaged. Gunk in the fuel can also clog things up fast. The system should be cleaned if this problem is possibility.
To use the late model aluminum head it should be modified to eliminate the lambda system.
I have both types of heads in stock if it found you need one.
