A month or so ago, there was a string of messages about mag particle testing and pressure testing etc. I had a head, I'd had mag'd and felt pretty good about it. Today a "new" guy at a machine shop punched three holes from intake ports to the water jacket while he was installing guides. Turns out how it'd been tested didn't make a dam bit of difference.
Hope you all have better luck for 2007 than I am so far.
