Default Intake gaskets

I'm in the process of reassembling my L98, and may have run into a problem. The factory intake manifold gaskets had small holes for the coolant passages, but the Fel Pro 1205 that I bought as replacements have large holes. Will this lack of a flow restriction cause any cooling problems?

I have the 1205 on mine as well with no trouble. If you run a search there and many many posts on the 1205. Reading back it looks like some have blocked off the rear coolant port and removed the small line tee into the heater core line.

Are the 1205's subtable with the stock heads? (if that's what you have)I though 1204's were used(again, for stock heads)

I have stock heads on mine, when I changed gaskets it was when I was putting the big mouth base intake on.
