1986 silverado 305 temp sensor hole size in head. Pics inside

[Nasty-LSX]

As some of you might already know, I am doing a 99 Vortec 454 swap in a 86 C10
The 454 has a 1/2 inch hole in the head for the original sensor. Is there a sensor for a small
block with a half inch thread or am I going to have to find a adapter of some sort? Thanks

You can see here in the pic, Pass side has a 1/2 brass freeze plug and driver is same size.

Don't understand why the head would have the 1/2 NPT threaded hole. But a pipe bushing that can be bought anywhere will work.
