Continental Prime Cylinders

I?m planning on a total new top end on my Superior XP O-360 that has millennium cylinders on it. After experiencing the typical high CHT?s, the results of such have forced me to make the move and additionally follow all recommendations for better cooling on climb.
Questions:
-anyone use Continental Prime Cylinders
-anyone have other recommendations

Frustrated, but determined to get to the bottom of this common problem.
