Leaking-coolant plugs on back of 243 heads

I'm leaking coolant and we think it's coming from one of the coolant plugs on the back of one of the heads. If this is the case, will I just need to replace the gasket/o-ring (whatever it is) inside the plug or will I need to replace the whole plug? We just got done with a H/C swap and we put the old 241 plugs in the 243 heads. Thanks.

I thought that they were the same ones. On my old plugs there as a seperate gasket for them, but on the new ones that I got the o rings are already on the plug.

i didn't get new plugs, so that might have been my first mistake. i think i'm gonna run by a gm dealer today and see if i can get the gaskets for the old plugs. if not i guess i'll hafta get new plugs afterall.
