Head Gasket Coolant Passage Openings

Head Gasket Coolant Passage Openings
Rebuilding my '97 Vortec, and these head gaskets only have 1/8" openings where the top coolant passages are, I'm afraid it's going to overheat and crack the heads. The gasket hole for the lower two coolant passage triangles seem undersized as well.
Am I safe to enlarge the coolant passage openings? Any history of issues with doing so?
And what about the oil passages? It can't be bad to allow for more flow, can it?
Did fel-pro design them to be exactly this restrictive, or is it ok to modify them?
Thanks in advance.
