Default bent valves!

hello everyone, today i picked up a 99' s80 with some engine problems . The timing belt skiped and it bent the crap out of some of the valves. I got a smoking deal on it so i jumped on it. Now, how hard is it to pull the head off and take care of this issue? i worked at ford for 4 years as a tech. Ive just never worked on a volvo. Watcha guys think? a couple of days?

It is not all that bad just time consuming. Also it is best to make or find the rear cam lock tool. Then before you remove the front VVT pulley if you mark it correctly then it will go back together really easy.

Check out this post it is for a 5 cylinder but is the same as the 6 cylinder.
