Well while putting my head back on again I managed to drop a washer from ARP kit down a hole. The hole is the biggest one in the head and is between the 2nd and 3rd cylindars as seen here:
I tested the head on a bench when I pulled it back off and in fact a washer will fall straight through this hole. I have shined a flashlight down the hole and I see nothing. I am 95% certain it went down this hole.
What do I need to do? I don't have a magnet retriever here and I'm not sure that will work. If it is stuck there how am I to get it out?
