You should have noticed that in the download page there is a description of an optional TTW esp called "TTW_Bobbleheads.esp", but it only says what the Repair Bobblehead does so you might not be sure if you want to use it or not.
That's why I collected all of the Bobbleheads and made a small list of what bonuses they give, the spoilers are the actual value of the bonuses in case you want to know it more specifically.
