...it's bad
but i also know of very few people with LS1s that plan on keeping the engine stock
it's fixable when you're inside, doing your thing...

I have it on both my motors and one of them gets pushed hard on nitrous at the track all the time.

If it ticks all the time, I bet it's a lifter tapping.
Neither one is a big deal. If it's piston slap, that's the way it's made. You just have to deal with it. If it taps all the time, pull the rockers off and check the pushrods. If there O.K., the rocker probably just backed off. Torque them all back down to 22 ft.-lbs.
Good luck!

It's normal, a new guy to the LS1 world , would be running for cover, it's common for 01-02's to make that noise.
Don't worry about, you just gotta accept it, kind of like oil compsumption

Actually hypereutectic refers to there being more than the eutectic equilibrium amount of silicon in the aluminum alloy. Basically the aluminum is super-saturated with silicon.
The rest of your post is good
