I have studs for my rockers, trick flow heads, 180 in lbs. ARP lube. No issues so far.

Rocker shaft bracket bolt stated at 15. Believe that to be correct.

You aren't using stock bolts which are ~17 or 200inch. It isn't 15 for stock bolts with oil.

Also, using the ARP lube reduces the amount of tq required to get appropriate stretch. Whatever ARP suggest for their studs, that's the number to use.
