With my new set-up, I bought, the PRC ls6 cnc ported heads, with the prc double springs tit ret's, pushrods, u/d pulley, 233/239 (233/239, .595"/.603") cam. Recent info was brought to my attention where a guy did a cam swap and his lifters would not keep up with his cam and robbed him a good amount of power, Should I be worried and buying lifters or would i be fine. And if so which ones should i look at or are good.

Thanks,
Mark

Unless you have reason to believe theyre failing, keep trhe stockers, as they should handle that cam and more.

if you got the $$ I would just buy new lifters and replace them while youre in there.

Replace with either stockers (new) or Comp 850-16
Everything else you're putting in is new, heads/valves/springs/p-rods/cam so why go cheap and leave a weak link.
You might be kicking yourself later.
Also change the plastic lifter cups, they are cheap.

Ok tho 850-16 are pretty cheap at around $210, where can i find plastic lifter cups. would i see any pwr gain with newer lifter? and while im at it should I replace the rockers? with a lighter stronger rocker kit.

Although I went with the Crane adjustables myself, most people will tell you to send the stockers out to Harland Sharp or something to have them reinforced. The stockers are very light as it is.
