JC, your engine is a work of wonder. I bet your engine is down 20-40HP just because of those exhaust crazy bends. You get nearly 340 CFM on exhaust that doesnt help going 90 degrees outside the head before the exhaust gets bigger. I know you werent responsible for this, but if it were me, I would call Tony and build some temp tubes to fit in the collector to get rid of those tubes with right angles just outside the exhaust port. I believe it is a major limit. We always increase the size of the tube before we do a bend in step headers. It makes power. You dont have mufflers in there do you? I am betting at least 1250HP right now.
