Hi Jon
I’d be wary of how you apply the heat. It’s an aluminium casting and localised heat could lead to cracks.I can’t remember if there is any galvanic reaction between brass and aluminium but that could be the reason they are so tight.
WD40 is not an ideal liquid to release stubborn threads. Plain old diesel is better or Plus gas.
Also I find Mole grips are ideal for rounding off the heads of nuts and bolts! A pair of Stilson May give you a bit more leverage? But again watch you are not creating teeth marks in the column!
Cheers
