Allowable torque on rod ends?

[rooster]

Re-doing steering this weekend, using QA1 xm series rod ends with 5/8 grade 8 bolts. Proper touque spec for this size bolt is 287 ft lbs. Will the ball of the rod end be able to handle this much tourque without damage/cracking?
xm series rod ends are made of alloy steel. I tried calling QA1 but they were closed when I called so any input would be appreciated.

On a MORE high steer kit I did the bolts were torqued to around 200 ft/lbs with no problems.

My 7/8"x3/4" bore rod ends are torqued to 150 - the biggest torque wrench i have..
