Please don't think that I'm picking on the engine, Jim. These are just things that I'm used to looking for and they stand out to me. If you were to have a bent pulley, you could kick a belt off at rpm. If you were to have valve float, you could lose an exhaust valve at rpm. In my mind, it's better to be proactive and say something, even if I'm wrong.

I don't see any reason why you need an 8000 rpm engine either, but if you're having valvetrain control issues, you could be down quite a bit of horsepower for the rpm range you're running in. I'd rather have more horsepower and not need it, than to be in a spot where I wish I had more.
