I am using rhoads lifters, which you end up setting like solids. Heater, if I were you I would get an extra lifter the same brand as the ones you are running, take it apart and make it solid. you just grind a bolt or something to length and stick it inside so the plunger is held up against the snap ring. No knowledge about the extra length, but a half turn on a 7/16" stud is .025" and on a 3/8" stud is about .021", which is how much most people preload a hydraulic lifter, so your numbers pass the idiot check if that makes you feel any better.
My length ended up being 12.014". Also, the pushrods bound on the rocker fulcrum, so they all had to be clearanced. The pushrods hit the inside of the slot, which couldn't be lengthened with my louis tool due to logistics, so I had to drill out the pushrod slots to 1/2" and install my guideplates. However, the guideplates are for 3/8" so I had to take everything apart and clearance everything for 3/8" pushrods. It was just a tad frustrating.
