Bend Back the fins or snap them off enough to be able to hacksaw down the side leaving 1mm of aluminum left then score it with a stanly knife or dremmel then press out the core very easy after that

what i do is drill right through the bottom to make the gas pasage then braze back up the ends when im done i think the bases of them are around 3/4 inch thick so they absorb a lot of heat when you put the channels inside
the base il draw a diagram for you and as for the sections i use copper plates 2mm thick cut into circles then drill a tiny hole in the centre for the captube then a larger whole to the side for suction i make around 4 of these then braze them in place one after another.

Here,s a diagram to help you
