Are these bolts stronger than the factory bolts?

Yes, ARP uses 8740 chromoly steel heat-treated to a tensile strength of 200,000 psi, which is stronger than typical factory bolts.

Do I need any special tools to install these bolts?

The 12-point heads are designed to work with standard sockets, making installation easier than with some other bolt head types. Refer to the manufacturer's installation instructions for any specific tool requirements.

Does this kit include new washers or gaskets?

This kit includes the 12-point timing cover bolts. It does not include timing cover gaskets or seals; these should be sourced separately if needed.
