Unlike head studs, usually OEM man bolts are just fine. There isn't much to be gained from going with aftermarket units.
However, when torque is greatly increased (forced induction), or if the engine will be used often at high rpm, it is usually wise to switch to ARP Main Studs or Bolts.
Main bolts can be used if on a budget, but main studs offer more consistent clamping force and should be the default if the bottom end will be experience extreme loads.
With the use of MRP main bolt reinforcement caps, these ARP studs are necessary.
