Are the L33 head bolts like pre or post 04' LS1 bolts?

I have a set of ARP head bolts sitting here from my 1999 LS1 engine and wasn't sure if they'd fit the L33 I got out of a (06? its a 24x cam sensor) silverado.

Anyone have any ideas on it?

Nope, you'll need the 04+ bolts. They're all equal length except the bolts along the intake ports of the head.
