Personally I would pull the cover also. That way you can find out if your bolts are corroded into the block or the timing cover.As a last resort you may have to pull the timing cover and then heat the bolts very close to the block to get them freed up.
i have had them stick so bad i had to break the cover off around the stud then it just turned right out it crazy what corrosion will do.
