on the back of each transistor there should be a bare metal face. the transistor should be isolated electrically from the heat sink otherwise the heat sink will be a shock hazard.I used some thin square plastic transistor insulator washers and white transistor thermal grease for good heat transfer. The grease goes on the back of the tranny then the insulating pad against the heat sink surface. But I agree with Peter, they should not get hot anyway. here's a pic from Google as an example...see the grease squeezing out the sides?
