I am not disagreeing one bit. When I first looked at my own picture it was hard for me to tell where the quench dome was and wasn’t. I enlarged it and could better see the slightly raised flat spot. I pulled a few diagrams from UEC and sent them off to the shop as well. In regard to the clay on the pistons I had two sets of heads done. What I was concerned about was that these pistons sat about flush to the top of the hole. Seeing that slightly raised area and then orienting it to the center of the block it looks like it would be tight enough to double check the clearance. Thanks to you both for the feedback and Happy Thanksgiving.
