P0301 DTC, 210k mi. Still has Orig. plugs: Replace all Coils too?

I am taking our 2013 to Gasket Masters in Manteca (Ca) tomorrow for a 9:00am diagnostic appointment. We'll see what they have to say after scoping cylinder #1 and the rest too, I assume. I did not pull the wipers and cowls after all, to check the plugs and scope #1 cyl. I did not have time.

 

@Mendel Leisk and I think

I dropped it off at the Manteca, Ca Gasket Masters this morning. Their prices were very affordable.
I was very pleased to hear the prices!
$1,850 Replace Head Gasket- Includes: Fel-Pro head gasket, Intake Gasket, New head bolts, new seals as needed, Denso Spark Plugs, PCV valve, Clean EGR valve & install a pre-cleaned EGR Cooler, Oil and filter change, One year, unlimited miles warranty.
• +$350 for OEM Toyota Water Pump, if needed.
• +$350 for Rebuilt & Resurfaced Head, if needed. He had two shiny rebuilt heads available on his bench! Surfaced (within spec.), Valves lapped, etc. (very impressed!).

Tomorrow morning, I'll hear back if they need to use a rebuilt head or a new water pump. Plus, Andres will be sending me pics I requested of the top and bottom of my head as well as a pic of the cylinders. I'm looking forward to learning what the wear and tear on our PIP at 214K looks like from the engine internals. I love this kind of detail. ;o)
