I'm looking for a little plug thats sits in the back of the cylinder head of a stock 460. This is for my old boat that my sister and brother in law bought. I have no idea what it's called or where to go about looking for them. The last ones I had my Dad gave me and he said he couldn't find them at that time which was 12 ish years ago. I have attached a picture. Any ideas ?
