ARP Head bolts
Hello,
Getting ready to torque the heads down tonight.
ARP paper in my box says 70lbs. Doesn't specify for aluminum or a different number for the short bolts.
I have looked over many threads here and it sounds like most go to 65 on the long ones and 60 on the short ones.
Do I follow ARP and go 70 on all or less on the shorter ones?
Thank you
Doug

ARP knows their stuff....always follow the directions they give. And use the assembly line they provide.

I used arp bolts on my Edelbrock heads. The doco that came with the heads said 65 ft pounds in three steps (40,55,65). So that’s what I did. Haven’t blown a head gasket yet.
Edit: Also always use a quality head gasket if you don’t want future problems. For Aluminum heads a Fel-Pro FE1010 is the go.
