1981 Porsche 911 SC 3.0L Engine
Posted to European Engine on 4/6/1998

The cutomer puchased parts from an aftermarket supplier. Everthing lookes good except the head studs have rolled threads for all but a 1/4" in the center. The part # on the package is 993 101 170 51. My problem is I'm not sure if these are a Streach Bolt...
