how much did they deck the block ?
how much are the heads milled?
they can both bring down the distance between bolt holes from bank to bank .
i recently had to over come this on my 427 , the intake runners needed to be moved out to line up with the manifold bolts , luckily i had a sheet metal intake and i used some exhaust manifold spreaders to separate the runners enough to get the bolts in , in your case you dont have that option. are the bolts to far apart or not far enough ?

If the measured distance between the intake manifold bolt holes in the heads are different than the LS1 heads than that shouldn't have anything to do with the amount anything was milled I would imagine. I just can't see a GM casting like that passing QC. Are you certain these are GM castings?

I had a decked block and milled heads on an SBC and when I tried to put the pain in the *** Super Ram intake on it the intake runners wouldn't line up and neither would the bolts (wouldn't seat all the way in the valley). Measure across the top of the block between the heads and see if the block has been decked, if so get to work cutting up more stuff... gotta love modding cars with a bunch of different people involved.
