Like I said before, your only loosing maybe a 1/4 to 1/2 a cc with those cuts. I see no reason for you to shave unneccisary material off your heads unless you are just looking for more compression. if your shooting for 11:1 and you come out at 10:9 to 1, I don't see any reason to pay to have more cut. I think you will be fine, and you'll have some room to clean up incase anything ever happens with the heads.

I used the auto calculator from a website found on a search from this site. of course i could of figured it wrong 
what did you use to figure it? If its 11:2:1 that will work great. i got 10:7:1 with this calc with -.5cc relief

That's the same calculator as the ross piston calculator I use to use. It dosen't figue anything past 0 deck on your piston height. when you enter.008 in there, your telling it .008 in the hole. You have to enter a negative number for out of the hole, and it will not allow you to enter a negative number. Try this one: http://www.rbracing-rsr.com/compstaticcalc.html It lets you enter the number the right way. Just read the instructions to the right of each box, and it will tell you to enter - or + for certain paramiters. It did show me 11:2 on your motor.
