Pushrod problems.

So I am building this 06 5.7 hemi for a future A body build and am running into problems. I milled the heads .030 to help with compression I grabbed my adjustable push rods and measured the length. called a well known hemi speed shop and the push rods they sent me are longer than stock!!! How does that work? If I have milled the heads the rockers are closer to the cam so the push rods should be shorter?! Right? Or am I missing something?
