Studs are good advice Marlin
Anytime a "long" bolt must be critically torqued, its best to replace it with a stud. With a V8 motor that will usually include the head bolts and the main bearing cap bolts. The reason for this ... the stud insures the torque is fully applied to stretch the stud as intended, whereas torque applied to a long bolt will tend to twist the bolt to some degree, like a torsion bar. The tendency for the bolt to twist makes it difficult to insure the bolt is stretched as intended, if it is not stretched properly the part shall not be clamped with the intended force.
