Need some help please

Anyone know the bolt size for the oil pump housing that attaches to the timing cover?
I read the torque spec is 18lb? The two inside snapped off while i was torquing to "18lb" .. SIGH
Hoping ARP has the bolts I need, I called them, they said they need to know what size they are.

It's not the bolts, you're over torquing them. 18 ft lbs is too high. 10 ft lbs would be closer to the correct torque value for those bolts.

thanks for the reply, I still need to know what size they are. I snapped two, I was able to get them out without any issues. Though I need to order a new set now.
