They would be useful only on an "extra-duty" block. Maybe I'm all wet on this, someone will know more... R.

I don't know the application for that part #, but If you plan to make enough HP or turn enough rpm to require 4 bolt mains I think you need to consider an "R" block. Two bolt mains with studs and aftermarket caps on the three center mains will provide sufficient strength for even fairly high horsepower levels.
