Sounds like the discussion we had back in post #4. I'm really glad you are measuring everything. I've seen engines built a lot tighter than what Comp Cams gave you, but those numbers should be easily achieved with a mild notch. Take good pictures. I promise there is someone out there trying to duplicate the build you are doing that doesn't want to have to measure everything. I saw a couple of these at Ford Nationals last weekend, but wasn't able to talk to the owners.
