Default LS7 lifter preload

I am installing PRC LS6 Heads and MS4. I bought LS7 lifters for the install, will i need to do any preload for these or can I just drop them in? Will I have to check the pushrod length if i am using stock rockers?

thanks

What is the part number on those lifters and where did you get them?
