While the 'compromise' on the gasket surface at the valve cover is not acceptable, I'm going to view this from the other side:
If I was a design engineer (which I still kinda am), and I knew that my intake was going on any number of factory or aftermarket heads, I would have left those ports just like that. Why try to make it fit? It's never going to fit anything perfect, so leave enough meat to work with, and leave it to the customer (and save the foundry money) to finish out as is. If you want a bolt-on, you gotta accept less than perfect. If you want perfect, you gotta have enough meat to get there.
If the foundry made them perfect for combo A, now all the combo B guys are returning it because it doesn't fit.
AND if the foundry made it perfect, the price would be up another 25%.
The difference: I'd put in the product description, "Requires port matching/grinding for maximum results with YOUR engine combo"
