Bad coils would cause the spark not to occur, causing the fuel air mixture not to ignite, dumping raw gas out the exhaust. A small amount of raw fuel may end up in the oil, if any , by leaking past the piston rings.
If some cylinders are not firing, that would put more load on the other cylinders that are, and the engine would run rough. Excessive load on some cylinders and no load on others, over time, may cause some cylinders to run hotter, others cooler... Plus extra pressure inside the cylinders running at full throttle...
Additional factors might come into play, such as the coolant running low one day, indeed, this may be enough to create a leak in the head gasket.
However, the above is only a theoretical argument. I personally have experienced a blow in a head gasket, in an old Saab, it blew during a period of hard acceleration.

One ignition Coil does not spark on 2002 Mitsubishi lancer?
I had similar problem...Ensure that when you replace the Ignition Coil, you also replace the spark plug (might as well do all 4) and the wires. This will prevent further Coil problems. The Coil could blow the plug or wires and when you replace the coil, the plug /wires will blow out the coil again. Also get a full diagnostic...specifically check to ensure the Head Gasket Cover is still good.
