They are indeed .030 in the hole. They are not stock pistons. They were replaced the first time I built this engine about 17 years ago. At the time, I let the machine shop get all the parts, they told me they couldn't find a "mopar" piston the right size, with full floating pins. So what they put in it is pistons that have 2 valve reliefs, but they are in the wrong place to actually do any good as valve reliefs. I don't know if the're chevy pistons or what. I'll post a pic later to show what I mean.
