First I’ve heard about the lifters, I don’t troll LS1Tech like I used to though. I did a quick search, looks like most failures are with a big aftermarket cam in non LS7 motors. Tons of people use the LS7 lifters including many engine builders, you’d think if it was a major problem it’d be more widespread.
Fuck it anyhow, the LS3 is the way to go for modding.
