I second sundog above. I have had my top end done by a qualified rebuilder 3 years ago who put it back together properly without updating to head gaskets and it is tight, dry and dynoed at 265 hp at the rear wheels in stock configuration (except for primary muffler bypass). In any case, the original issue that Porsche had with the cylinder to head interface was not an "oil leak" but minor sweating of oil around the head seal. Significant oil leaks are almost always traced to some other cause (oil lines, return tubes, valve covers etc).

Good luck!
