intake studs

Ok engine guru's enlighten me. Murphys law came into play today in a big way LOL.
I put the gasket sealer on and placed the gaskets, when I opened up the pack of RTV to do around the water passages and where the cork should have been the tube opened up on the side {lesson to self..do not use knife to open package}. The beads were put on useing my finger. Next I noticed the gasket need to be pushed up a bit for the holes to line up...gasket ripped a bit throught the little blue bead on the gasket, I hope it will still seal, it was not near the water passage.
What I would like to know is what could happen if the gasket does not do its job properly. I am pretty sure that it is not going to leak anti freeze, that I sealed up well. Can more silicone be added after to the ends if I did not put enough on.
Thanks guy's
