Engine Impact of not putting thread sealant on #11 head bolt

Got a new to us 78 CJ7. Had the engine rebuilt and they didn't put sealant on the #11 head bolt. Coolant was pooling just below a number of the head bolts. I pulled the head bolt and added sealant and torqued back down, but still getting coolant seeping out. I know it could have been a cracked head or blown gasket, but curious if anyone has experience with the impact of forgetting the thread sealant on the #11 bolt. Worried that coolant pressurized and maybe blew out the head gasket. Anyone have experience with this?
