Had a discussion about this with the guy from Comp-u-flow at Carlisle. He says one of the biggest mistakes is overtorquing those bolts. 30 lbs is all they need regardless of the setup. No matter what you're using its still going into the same ALUMINUM hole !!! Also, your turned down bolts were likely for really thick-walled shafts. Harland Sharps don't need turned down bolts or studs. Studs go in finger tight, the nuts get torqued.

The trick is to call ARP and tell them you want a rocker stud kit for a BB Mopar and they'll put together exactly what you need for about $60.. They know what you need but haven't made it into an actual "kit" as yet. Note: the studs are not all the same length - hence telling them what you're doing!

... do not overtighten. call Harland Sharp and ask them about it.
the paper work that comes with the rockers should have the recommended torque.
you don't want to torque those down the same as you would for the same fastener in a different application. i would suggest no more than 30 ft. lbs. with 30 wt. oil. it would take 40-45 to stretch the stud and that will distort even a heavy wall shaft like you have. that's the reason i use the loc-tite.
