Adam- I'm using Gary and Ken at Larry's Auto Machine in North Stoneington. Kenny was one of my guy for years, but he closed his shop last summer. That's where I bought the head equipment from taht you saw in my garage... So now I use Larry's. So far, two LA blocks and one 383 block and absolutley no issues. Plus, he's got in house computerized dyno cell and an SF600. He completely built Tom's (MOPARTS Tom, 800+hp) blower engine too. In fact, it's got my old gear drive on it...lol.
