You can run into major problems depending on what Mosfet is used and the mounting kits. Some use plastic screws, others use a insulated guide for the metal screw. Both can have a failure soon after use, where the screw or guide will soften due to heat, and then there is little heat conducted to the heat sink. Make sure you use only the best mounting hardware. I have gone a different way, I float the heat sinks. Also you could use a spring device to press the Mosfet body to the heat sink.
