Need a bit of guidance

if the lifters are hydraulic, then valves revert to closed once oil pressure is gone. so...if it's not running. All rockers should be sitting at the same angle. Is this what you meant by different angle? it is incorrect if they are sitting staggered while not running. Next part...no. you will not have any valve to piston issues with that setup. I run a 689 lift with 2.1 valves and had a mile.
