Bolts vs studs

So im replacing the 4 studs that mounts the trans to the motor…if anyones been that deep before youd know the trans slides on to the motor then the studs are installed…stupid design but it is what it is. Instead of pulling the motor and trans out as one i went a different route and removed the studs and slid my motor to the side to access the sheard off stud. Im thinking of replacing them now with grade 8 red loctited bolts, any thoughts?
