Can someone give me a part number for the plug that goes inthe rear of my TFS 220 heads. I was about to start my AES 390 and as I was putting in the antifreeze it all started coming out of the the hole in the rear of the head. I read that this hole is drilled out for aftermarket water temp gauges but I just need to plug it for the mean time. Can someone tell me what I can use to plug it. Please give me the thread pitch and the length. I believe I read it was 1/2 npt can someone confirm.. Thanks
If it is stock your temp sensor will thread into it. GM sells the plug if it is still that thread, but I don't know the number by memory. I buy them from Scoggins Dickey.
