Hydraulic lifter question + 1.6 roller rocker

I adjusted my 283 lifters yesterday, just to make sure that everything was properly set up.
All were adjusted to a turn preload.

All but one behaved in the way that could not be compressed further by hand after adjusting the preload.
The last one could be pushed by hand easily to what I believe is bottom of the lifter.

I turned the engine over twice to double check and even re-adjusted some of the others, but this one kept acting differently.

Is this normal?
Is this lifter dead?

Should it possible to install a set of 1.6 roller rockers on a set of 462 Camel Humps with press-in studs?
Besides the piston to valve clearence of course...

Perhaps the lifter in question l just wasn't pumped up. If the engine was never ran before it a good possibility. If the engine is well run, then maybe that lifter bled down under sitting spring pressure. It's hard to say without letting the engine run and building oil pressure to feed the lifters.

if you re adjusted a few after turning the engine over they are most likly to tight now as for the fact of when you turned the motor over you blead pressure opff them and then when you checked them again they were loose. I would start over and do them all again and thn set the one that didn't seem right so it has about the same amount of threads left over as the rest and then adjust them with the engine running and have a helper start and shut the engine off so you don't loose to much oil.
