Use the stock ones unless they're no good, then use LS7 lifters if thats the case as they are supposed to be stock replacements but are still a little differnt.
But if the stock lifters are good save yourself some possible issues and use them.

Really? I'm not gonna run into problems just using the stock lifters for sure? Isn't the xpz supposed to shift over 7k rpm tho?

if you rev that high and using stock lifters an push rods be expecting a few bent push rods. na i wouldn't recommend going over 6300 and i run o-er lifters... little noisy but i know i dont get "pump up" at 6300rpm

ugh I'm scared "What you will notice about our dyno chart beyond the insane peak HP number is the power curve. The power did not fall off all the way to the 7k rev limiter. Simply stated, the ZZP XPZ cam produces more torque, peak HP, and more average power than any cam currently available for the 3800 engine. No other cam profile even comes close. If you're serious about performance there is no other option for achieving this level of performance." THE 7k REV LIMITER??? what should I do I just don't want my stuff to blow up when I'm driving

he was shifting around 6800 iirc and i think a l26 rod went on him. just thinking your prolly goin to DD and not a push the limit gutted car is all.

Pretty sure it was 6900 or 7k but the rod went due to no fuel pressure... Lol

You mean loss or low fuel pressure that would cause lean conditions and spike kr.
