Rocker arms for Speedmaster LA heads

new rockers? new shafts
used are they going back where they came off?
inspect all the cups, any wear pitch them especially if new or mismatched pushrods
we had to run that much pressure with stock rockers can be done
put rev lube on the bottom of the rockers when installing
run oil through the pushrods will help pushrod cup wear and push thrpughs
btw run the stiffest pushrods you can fit
how much additional lift over stock- .050? you should be ok maybe shim shafts like .025-- gotta check
talk to rocker arm specialists about iron, bronze bushed iron etc if you go that route
