The Ford Barn - View Single Post - didn't use Permatex Thread Sealant when installing heads

I messed up installing my cylinder heads. Did not know you need to use a non hardening Permatex Thread Sealant on studs. Well you guest, it started leaking out of bolts about 2 hours after adding antifreeze coolant. I drained coolant but am concerned the coolant may have made its way into the cylinders themselves. I used copper gaskets with permatex copper seal spay on booth sides of gasket, two coats. Since I have to take all the nuts off and reinstall with sealant should I take the heads off and check the cylinders? Will this destroy the copper gaskets as the copper spray may stick and tear the gaskets apart? I don't want to spend another 120 on new gaskets for my newbie mistake if it is not necessary.
