Dennis for 600 ci the Profiler 355 is a better head. With cam and compression it should go over 850 with reasonable rpm's. The key to making power with these big motor's is valve lift. The more lift you throw at it the more expensive it gets and attention to detail is extremely critical to try and make it live.

One more thing I would not go to big on the runner CC. Will make it a turd on the bottom end.
