1970 911T.  Recent compression test on cylinders indicated 2 cylinders at 50-60% compression (well below what is normal).  It is a good driver today even with these underperforming cylinders, but clearly not perfect with backfiring at times, a little rough at times although carburetors adjusted and well timed.  It is the original numbers matching engine and holding long term.  I am told a rebuild $20-$30,000 and possibly more.  Once engine is opened, could and will be other issues since original engine with no prior rebuild.  How do I find qualified shop and is the estimate correct?
