It's on the high side for those lifters.
I bet you hear them pump down after down, tick tick tick...one by one...how do I know? Cause I have a bit less seat load on mine @130-135 lbs...but less open than you.
It's been said 130 was about all you want to run on them for seat with an iron core roller with open around 330.
Preload was stated ... up to .090
Should not have ticking on start up.
Might be a loaded question, but… IF a person was to experiment with this lifter, & take the hydraulic insides out and replace with something to make it a solid roller lifter, would that increase the spring loads it would be able to take?
I don’t know how much abuse the roller wheel axle could withstand either, should something like this be attempted…
