This is the "hot" 051/052 cam set -- any 051 cam should fit just fine, although I'm sure if I'm wrong that someone else will pipe up.

Cam is fairly easy to change on this engine EXCEPT for the angled bolt on the rear cam tower. Right is better than left, but is often impossible to remove the bolt with the cam tower in place, they must be removed together.

DO NOT switch left and right rear towers, you will get oil starvation and another ruined cam. Replace the plastic "drip" line and fittings when you replace the cam, you will surely break the old ones. Verify that you have oil dripping onto the cam before running the engine at road speed.
