How much milled off heads to raise compression

I've never heard so much hearsay in one thread in quite some time.
First off aluminum heads won't cure your 10.5-1 race fuel issue LOL...
Second you can hit your factory Pistons with 150 shot all day long and not do any damage (IF DONE CORRECTLY!!)...
Nitrous favors lower compression..
Just what I want to hear I’ve built a lot of safety into the nitrous. Engine shutdown if fuel stops, from dash adjustable timing, 2 stage nitrous controller,fuel pump for nitrous only. I read that nitrous prefers low compression.
At this point it is a no brainer.
Nitrous is almost free horsepower vs
New pistons at 400 a pop not to mention pulling the engine and basically doing a rebuild. !!!!!!!!
