Hello guys I am reinstalling a transmission on my new engine but I have this plug it is loose in the hole is it normal once I put the transmission on the engine will it fall off in the case or it will stay in the hole ? Engine m44b19 transmission Getrag 220

I have 3 threads that are cooked on my m44b19 cylinder head for the valve cover

I have a gap between the helicoil and the thread of my bolt as shown on the pictures

Is this good enough or should I get helicoil that make the whole thread?
