Mainline Vent openings too Small?

I have two main vents, which you'd think would be adequate for my smallish system, but they are only 1/8" each (radiator size). Is it advisable that I tap these old pipes to accommodate 3/4"? My system seems to be working fine now, but this might save me some dough in the long run. What are the risks in tapping an old pipe like this? Basically I don't want to create a disruption/leak in the adjacent pipe joints, etc. Thank you.

Pictures of what you have would help immensely. It's hard to say for sure without seeing what you have to work with.0
