I did it....914/6 powered by a 3.0. 120K on the motor, rings looked good and the pistons and cylinders were good as well. The head studs were all replaced.....well worth the addition.
The bad.....
Cam wheels are different, you have to grind off a lobe that will hit the oil cooler.....the 964 cams have a power sterring take off....few other issues that were a bitofapisser....
