ARP finally fixes main stud to oil pump problems.
Let me ask you this. Would you put studs on all the left side of the caps and bolts all on the right side of the caps when you build your engine? Im sure the answer would be "Hell No!". Then why do it to just one? I have built a ton of SBM WITH the rear cap studded on both sides. It can be done, just takes a little work. If your not up to doing the work, then just put bolts back there, dont mix them up.
