How much milled off heads to raise compression

Now remember before you call me cute or smart *** you're the one who made your snide remark to lure me into this conversation...
The op had described somewhat of stock engine and aspirations of doing 11 seconds. Also aspirations of using nitrous. then someone came in and said that he cannot use nitrous unless you changes his Pistons can't be done...
Then someone came in and said that you can use higher compression if you have aluminum heads... (and was cautioned in a personal message not to use the disagree button or I would be banned from the Forum but a monitor)
Whatever you want to make up to make your end of the discussion sound better is fine with me. I always wanted aluminum heads I got aluminum heads and now my old heads that are not old but in very excellent condition will go on my next project no big deal...
OP doesn't have to do anything he can just sit back and watch this entertaining thread instead of spending his money at the drag strip..
Lure you into a conversation lol, you do that all by yourself, I will not muddy up the thread anymore.
