Basic NA build, what am I missing?
Car is a 99 Vert, manual, 26k miles
Mods so far:
XS Power long tube headers
TSP 228r cam (228/228/.600/.600/112 LSA)
Blackwing air filter
160* thermostat
25% U/D pulley
Car dynoed at 380 rwhp, 362 ft/lbs
Next I would like to port my throttle body, get an LS6 intake manifold, and a pair of PRC stage 2.5 5.3 liter heads.
What else can I add that would add power?

When you replace the heads, you'll need a better intake manifold than the LS6 unit and you will need an LS2 throttle body to allow the engine to breathe properly. A FAST 92 intake would be a good choice - a ported FAST 92 would be an even better choice. You'll most likely need new injectors too!

If it were me I'd stick with the LS6 intake and a nicer set of heads. 243/799, etc. Porting would be a good idea too.

I would do A/I heads (243) or the MMS as cast heads. Agree on the cold air intake and the clutch. When I did my heads/cam, the clutch wouldn't hold on the dyno. What a pain. And careful being too aggressive from a standing start or you will be looking for rear/transmission parts too.

Mods so far:
XS Power long tube headers
TSP 228r cam (228/228/.600/.600/112 LSA)
Blackwing air filter i would buy either the callaway or the vararan intake myself
160* thermostat i would skip that on a n/a build really no reason to have it
25% U/D pulley
get a ls6 intake with throttle body combo
243 heads , make sure you do the upgrade on your valve train as well
i would add the rear steam port's as well...
Car dynoed at 380 rwhp, 362 ft/lbs
Next I would like to port my throttle body, get an LS6 intake manifold, and a pair of PRC stage 2.5 5.3 liter heads.
What else can I add that would add power?
