Ls1 head simple upgrades

I have a 2000 Firebird A4 boosted at 10 psi stock engine 168k, spirited driver but rarely in boost.
I need to replace a bad lifter, while in there I'm considering upgrading springs pushrods and rocker arms keeping the bottom end of engine stock.
Any recommendations for parts better than stock without breaking the bank or should I just keep it stock?

If your not changing the cam I would just keep it all stock...
Question.... How can one be a "spirited" driver, but rarely in boost?

Springs are a good idea at 10 pounds. Pushrods only if you're cammed. Rockers not required.

Completely stock just added rear mount turbo, dyno tune around 500 rwhp 580tq.
Setup on car about 4 years now.
In boost enough to get me in trouble at times but it's nice just to cruise around calmly in a clean rare car as well.

What's recommend for head bolts, my understanding is I cannot reuse the stock ones.
Was considering ARP 1343609 head bolts.
As for lifters I thought of getting ls7 with trays.

That's funny right there.

If you're already getting 500 Whp, then I would just replace the lifters and springs. I don't think head work will make a huge difference without a different cam.
