Cutting coil questions

[GMC Guy]

i know this is a common thing, but i'd like to know exactly what i'm doing before i tear my truck apart and start cutting stuff

i only want to cut a half coil (for a 1in drop) but if i feel it could come down lower, i can always cut another half. dad always said you can always cut more off but you can't put more back on

so i have all the tools needed: ball joint/tie rod separator, bfh, and a cut off wheel. not gonna use a torch lol

my questions are, how is the spring going to fit in the pocket and on the lca, if i only cut half a coil off? is there any little things i need to watch out for? other than the spring flying out at me....

and lastly, has anyone ever put factory 6cyl coils under their sbc truck? i would think it would be a weaker spring, providing some drop
