I need a new head gasket so since everything has to come apart I'll also change valve covers, and timing chain (depending in what condition it's in).

Anything else I could/should do..maintenance or performance?

Preventive maintenance I guess..it'll be changed if it needs to be, since it'll be out anyway.

while you are in there you might as well do a port & polish on the heads, & maybe install a more aggressive cam:D

timing chain tensionner. Unless something is broken, you dont really have to replace timing chain. But sometimes the tensionners get loud as shit, and they're cheap, so might as well replace it.

if you're gonna do a headgasket, i'd probably seafoam the motor right before, you'll see less deposits in the motor when you take the head off.

if you're thinking about boost, might be a good time to drop your CR, get ARP head studs, etc.
