Get it tuned up and let it rip... doesn't really matter the build, you'll find out once you pound on it. I'd set total timing at 36*, set the carb for best vacuum at idle, change the oil/filters, check the plugs and roll. Hammer it try shifting at 5800, then 6000 if it feels like it's still pulling try 6200... You can also add some timing until it pings or falls off.
