Robert,
I read your post again.....I did mill the intake side of the heads, I did not mill the intake.......I read your post to quick and interpreted it as milling the intake itself......
When milling the heads over .030 you will want to mill the intake side of the heads to achieve good fitment......you will likely have to mill some off the intake side of your heads to get good fitment...... not uncommon at all....of course you may get lucky with your setup, but I would mill the intake side of your heads to ensure good fitment of any intake you wan to run....
