Timing Belt - Did I mess it up? 850

I have a 96 850 Turbo with 138k and for the past month have been learning as much as I can about changing my timing belt. I've been on everyone's message board and researched all threads dealing with changing a timing belt. I have all the parts, from FCP, and a lot of tools including air tools. I'm changing out the water pump (Hepu) the idler pulley, tensioner, tensioner pulley, Conti timing belt, and a new serp belt.

All of the timing marks lined up perfectly and I removed everything except the crank pulley. I thought I could get the belt off without removing it. Wrong! I had to cut the belt to remove it. Then I decided it might be better to remove the crank pulley. I used my impact wrench w/30mm socket and off came the nut. I then tried to remove the four 10mm bolts on the crank pulley. All but one came off. The one that was frozen in place was pretty high up and couldn't get a wrench (impact) onto it. So, I reinstalled the other bolts on the crank pulley so I could turn the crank with a screw driver to the point where I could use an impact wrench. I turned it slowly about 1/4 - 1/3. Unfortunately, the bolt head rounded off and now I'm trying to use a 'bolt out'.... without success.

My question is...Did I mess up the valves or bend the valves by turning the crank? I only turned to the point when I felt some resistance and then stopped. I'm concerned that I may have bent the valves and will have a disaster when I put it all back together, start the engine and ??????.
