Hey, Hey, Hey, I'm the dummy that wrote starter on the bag three years ago, give me a break! They are not starter bolts, the new starter is installed. I think they might be valley pan bolts. I was going to build the engine back up myself, I took it apart and to the machine shop, but decided to let the machine shop go ahead and put it back together. Of course, they didn't have these bolts, so they used something else (cringe). The GM parts catalog says they are 5/16-18-2 but the Classic Industry catalog shows a bolt similar to what I have. I think they are the Valve cover push rod bolts. Thanks for the responses! I really appreciate the help.
