Verdad Gallardo Yep you could just prime the stock lifters, or even mod a stock lifter so it is solid. The adjustable push rod is cheap, just buy one and you will be able to figure it out with the info on this site and others.
Yes. But to some people, and depending on the valve spring, it's a pita just to remove them. Especially if the motor is in the engine bay.

if you are going to mod your motor...best you learn wtf is needed to do so or have someone who does do the work.
a "guess" would be 7.100" to 7.150"...but that is just a guess.
pull any RR on a cyl. mark the valve tip with a sharpie, put RR back on and turn motor by hand 2 times, remove RR. if witness mark is dead nuts center your pr are fine. if it is closer to exhaust than intake than you need a shorter one,\.
typically you need a shorter PR with the mods you have
