Thanks everyone for the feedback. I agree on the valve issue. Everything I've read clearly stated that if I get a GM vehicle with an LS7 that replacing the heads should be the first thing that I do to prevent dropping a valve. I would likely do a cam at the same time. I've seen heads/cam/intake/exhaust on these cars make 600+ rwhp. I think that would be a blast in a car that is pretty much a purpose-built racecar from the factory. The car in the video link below made 632 rwhp.
