can someone please recommend ARP timing cover bolt set?

Hey folks,

my stock hardware is coming apart. Two of the upper studs that retain the water pump have broken in the timing cover! Summit has several timing cover bolt sets available and I am confused as to which one I need, some are spec'd for Aluminum water pump, cast iron water pump...I am using a Bosch direct fit replacement pump on an otherwise 'stock' (on the outside at least ) engine.

Also, I would really like to replace all the studs that hold on the accessory brackets...mine are really coming apart!

This hardware looks relatively inexpensive in the scheme of things but I am concerned I I will order the wrong set....so please share if you are in the know!

Thanks
