If doing a fully built motor do ARPs

If boosting stock leave stock alone



With said if you rattle that motor youll flex that crank

Yea I would say its worth doing the studs if you already have it apart.

Pulled engine out tore it apart and studded block with arp studs .Got back together and running 250 miles on it new build . after 500 mile going back to mobil 1 oil . conventional rottella 15-40 .Cant take the heat .

I picked up studs for mine while it's getting built. I actually went with arp for nearly every bolt on or in the engine.

tim wellington

never .HONED it.we check it with studs before and after HONED clearance change .001 on every cap except number 1 it stayed the same for some reason .
