Bob:

2.7's (and prior) all had plain steel studs, top & bottom.

Its a VERY durable setup as long as the case has been properly prepared and you keep strict control of oil temperatures

According to Bruce Anderson's 911 performance handbook the 77 engines had dilivar lower studs. This was the first year for these.
