is it ok to use a impact gun on the flywheel bolts and clutch bolts for installing them

 

When you are removing them it is OK, but when installing them torque them to spec with a torque wrench.

For the smaller clutch bolts, torque them down and use some red Loctite on them.

On the big flywheel bolts, turn your impact gun down and pop them on evenly, going over them a few times in the criss-cross pattern.
