Hello, You don't need any special tools, just mark everything with white out for orientation. The cam cover will pull right down with the bolts starting from front to back and the 3 turns each until torque spec. Please do not use RTV your engine will leak oil. Use the Volvo gasket material, it goes on very easy and doesn't clog oil holes. Make sure you use an assembly lube on the cam and lifters. If you have an oil adjusted cam gear just make sure cam is straight across and the advance gear is rotated clockwise all the way, then the timing will be right. I have done about 50 or 60 head gasket jobs and I have only used a tool once on a 2005 with two cam advances for a oil seal repair. Head bolts can be reused if you can do the measurement on the bolts, I have reused them on about half of the jobs and had no problems. Make sure you use the assembly lube on the bolt threads before installing, not all the way up just the first 10mm. after everything is torqued down and your ready for timing belt turn camshafts to make sure everything is turning free, bring back up to your marks and then install timing belt. After that, everything else is a piece of cake. Good luck and just think about each step you used to take apart and do the reverse.
