Remove the head, purchase a threaded insert if available or used head/new must have new head bolts, head gaskets and go for it. I don't like a helicoil repair in aluminum.

Not that it helps you now, but I bet it's the bottom one on the port side. Had a Mercury master technician in Norcal tell me he always removes the port side pan to change plugs. Doesn't take that long as opposed to screwing up the threads on the bottom plug.

How many threads do you have asking the same question??? Only ONE is necessary......Goggle "timesert"
Steal sleeve threaded insert. I personally would never use a heli coil when I can get a insert. Put hundreds of them in aluminum heads, in the automotive world.
I wouldnt use an insert. I just went through this. I bought a new head

Replace the head. I don't care for any kind of insert for spark plugs.

thanks , I pulled the head off and ran the tap in from the back .new gaskets new plugs and it ran great all day today
Should have used a thread chaser instead of a tap. A tap cuts bent threads out, A chaser will straighten them in many cases without removing metal
Thank You Leon Pugh
Did you replace ALL the cylinder head bolts, they are single use?
This.
Have used them many times in racing applications because stuff happens and it’s either get it done now or go home with your tail between your legs. We seldom rebuild back home just because of the insert
You get over the theoretical debate when you witness their performance and durability because you have no choice.

Steel sleeve thread-sert type insert is the way to go. Have to be VERY careful as the margin for error on the plug angle is about 1.5 degrees.
