They were supposed be close to 800 according to the prior owner.

to keep all the open holes under the water so pressure is still good?

usually there will be 4 holes that have been pluged from the factory which represents a more agressive x-dimension. there as you may not need to go up as much with shorty due to an increase in slip with going too high.
they are pluged so they dont allow the lower to suck air or to an extent bleed off water p.s.i but most the air part.
it really helps to have access to -2 lowers and spacers in 1/2 inch increments, a pail of gear oil and a solid day to truly test and find the sweet spot.

best of luck.
