Far as I recall they are, I have always had ARP main and rod bolts though so I don't know for sure.

The ones on the side are reusable.

Hardware

Most of the hardware is torque to yield including head, main bolts, flywheel bolts, and dampner bolt. I highly recommend you use ARP head and main studs and replace the other torque to yield hardware with ARP bolts.
