Hi,
That's a tough one without seeing it. Can you take a couple of pictures of it and upload it for me to see?
They sound like possible valve body bolts if they are threaded but have a smooth portion towards the top. However, this type of bolt is used in other areas as well so it is going to be tough to place it but we are going to need to see it to have a shot at it.
I attached the picture below of what these normally look like.
Let me know.
Joe
