You just can't expect a good torque on rusty bolts in rusty holes. Minimum is to run a tap through every hole. Next improvement would be new bolts too. Ultimate is studs and new nuts, all grade 8.
Though I had thought the longer blocks have more space between pairs of cylinders, and don't blow as often,
