carb'd intakes and EFI intakes will have the same positioning of the intake runners. 0.030 over should be fine, I did my 5.3 with the Edelbrock Performer RPM intake with no issues, I was milled 0.015. I am putting a new Edelbrock Performer RPM intake on my LS1 tomorrow with 0.020 milled heads and don't expect an issue.
