What would cause lifters to pump up and rockers to break in small block 350 with vortec heads?

It sounds like there is something wrong with the way the rockers are being adjusted, or perhaps the wrong parts are being used.
Try this method from Chilton's for adjusting the valves on a hydraulic cam:
With the engine at #1 TDC, you can adjust 1, 2, 5, & 7 intakes, and 1, 3, 4, & 8 exhausts. Rotate the engine one revolution for #6 TDC to adjust the rest.
To adjust: Tighten rocker nut until all backlash is eliminated by feeling the pushrod between your thumb and forefinger, then tighten an additional ¼-1/2 turn for preload.

What causes premature failure of a new camshaft in a small block Chevy?
It's usually caused by improper break-in procedure, but can also be caused by burrs in the lifter bores preventing the lifters from revolving or improper break-in oil.
Small block Chevy lifters not rotating.2nd new set?
That's usually caused by not following the break-in procedure. It's important to get the engine running quickly without cranking the starter much, and get it up to speed right away. If the cam has suffered wear from the lifters not rotating, it will need to be replaced.

Why does preloading my hydraulic lifters keep my 350 Chevy from starting when it starts without any preload?
The pros say, "Don't preload the lifters." When they are preloaded, they are basically solid-lifters until they get a chance to cycle a few times. With no 'give' in the valve train, things can break! Either way, don't wrap the motor past 2000 rpm for a few seconds. The parts gotta get "friendly".
Can you escape finally block?
You can only explicitly escape from a finally block by returning out of it. A break statement is not allowed there.

Do you need new hydraulic roller lifters if you have a new cam?
Officially you should change lifters anytime you change the cam. In real world use; unless the roller lifters have obvious, visual damage, missing pins, wear on surface of the roller, then it is not normally going to be a problem. In the case of flat lifters, you should change them. The cam of flat tappet (regular) lifters, have a slight bevel to the surface of the cam. When the cam and lifter are in operation - this causes the lifters to rotate in their bore. After/during break-in, there is some wear on both surfaces and they end up with a pattern which is unique for each bore and and each cam/lifter combination. If you change either the order of the lifters on the original cam they meshed with, or install a new cam or new lifters - there is a very real chance of accelerated wear leading to failure of cam and lifter. What is worse - the resulting debris can follow the oil and ruin bearing surfaces throughout the engine. Your money, your choice.
