Compression question

I have a Stock block deck, stock head gaskets, stock combustion chambers, stock valve.

My heads were milled 5 thousandths. .005. Will that have any effect on compression ratio in a 95 LT1 with aluminum heads.

Yeah, I knew that. I was just curious if it would be .1 or less or if anyone knew what it worked out to be?

If you would have gone w/ the impala headgaskets or felpro 1074's it bumps you up .2-.3 ish. The people I asked said the 1074's bump you from 10.4:1 to 10.7:1 the impala is probably even more.
