I didn't say that a restrictive block is a bad one. Did you experiment with different pin heights? I'm saying so because I'm afraid heat is being forced to spread laterally and not both uniformely laterally and upwards throughout the pins. Keep in mind that you could also lower your baseplate when making higher fins/pyramids which would further increase performance. The only way to know for sure is to experiment or simulate using a simulation program.
