I just moved to Washington D.C. and was wondering in anyone has used or knows of any independent mechanics in the area and trusts them to do a top-end rebuild on the S38B36 motor. The head gasket on my 91 M5 has blown, and I've lost some compression. Figure I'd redo the valves and replace a few parts while I'm in there. The BMW dealership in Oklahoma wanted to charge about 8K for the job.

Appreciate any feedback!
