Anyone know why so many suggest the 930 valve covers? I should be asking over there, but don't want to highjack their threads for such dumb questions. I have so many.

You said it has been rebuilt? what was done to it? If correctly rebuilt (time certs, etc.) 2.7s can be great motors. What year 911 was the motor from?
Are turbo valve covers necessary? My valve covers are the originals and have never leaked a drop.
IMHO there is a LOT of misinformation re: the 2.7L engines, a lot of it from people who have never had one and are just passing on the "conventional wisdom" they have heard. If properly rebuilt, they really present no more issues than any other flat 6..
2.7s from 75-77 were definitely more prone to issues because of the 5 bladed fan and thermal reactors but these issues can be remedied.
Take some time and find out what was done on the rebuild and you can make a much more intelligent decision re: the car and motor. I wouldn't blow it off just because of the 2.7.
