If I’m reading everything correctly(based on the .130 scrub comments), it sounds like you were running the 1.7 rockers on the motor?

If so, it didn’t have nearly enough spring.

I would consider the 135 on the seat no more than “adequate” for those lobes and the typical 1.5 aluminum roller rocker with its “high moment of inertia body”........ if 7000rpm operation is really part of the plan.

My 383 would turn 6900-7100 thru the lights(depending on weather), with a cam using lobes from the same family, the same springs with steel retainers, and Isky iron 1.5 rockers that had been lightened.
No evidence of any unhappiness after 100+ dyno pulls and 3 seasons of bracket racing.

Both the higher ratio and “heavier” rocker will require more spring load to achieve equal rpm as a lighter rocker/lower ratio combo.
