GMC ENVOY BLOWN HEAD GASKET PROBLEM

2004 GMC Envoy • 170,530 miles

Im having a random cylinder misfire after changing the coil packs, spark plugs, and having the converter removed because it was clogged up. Would a blown head gasket cause this. If so is there a fairly inexpensive way to fix this.
