bit more of an update , not had much workshop time lately cos of various reasons ,
but milled the fins on the new top ends so they fit the rcmk case ,
only three sides need machining , flywheel side for clearance, and between the two to bunch em up a tad ,
then the ribs on top need taking down so the heatsink fits,
took the ribs off, and bare minimum into the surface,,
i could have done with spinning em in the lathe to get perfect, but would take an age to set up with 4 jaw chuck etc,
so theres a 0.15mm square that needs dealing with around the plug holes,
tops are perfectly flat and even, but gonna do two 0.15mm or 0.2mm square pockets in underside of the heatsink so it sits flush to the heads ,
then need to mark then drill and tap the four mounting holes for the heatsink,
