    Default ARP Studs, AFR heads Torque spec!

    IIRC, I've used three passes using Shbox's chart, setting the last pass at 90lbs. Pretty sure that's what I've done in the past ... but I can't get anyone in my local circle on the horn to be sure.

    Anyone out there know what specs would be used for the ARP Studs on the LTx block, using the AFR (210) heads?

    I'd love to get this done today, if possible... . (Thanks in advance to anyone that shares).

    I usually go 85lb on the last pass but I don't see 90 hurting anything if using a good wrench, proper lube, etc.

    OVA1, if you're using the ARP Ultra-Torque Lube 80 ft-lbs is the spec. If you're using motor oil aim for 85-86 ft-lbs.

    Divide the final torque by 3. That's your three stages.
