You can do it without pulling the head. Like I said, make sure the dial indicator is parallel with the pushrod and lifter and do the degreeing. I've done dozens of them in the car with the heads on. You'd be surprised how many cars are under performers because they didn't degree the cam. Just take your time. If you get stuck, you can always call someone. I can walk you through it if you need help.
Just hate to see you do more work than need be.
