Performance upgrades
Hey guys new the the vette game. Just picked up a 2002 z06 with cam(don't know the specs which sucks) 243 ported and polished heads upgraded valve train-kooks long tubes-unkown xpipe no cats-broke stingers-vararam air box-think that's it for the motor. Wanted to do new heads intake maybe throttle body and maybe new cam that goes with the right heads. Just not sure what's a good combo and if I'm gonna need fuel components or dif oil pump. Just wanna make sure I don't buy the wrong stuff or stuff I don't need lol. Thanks in advance.

New heads are really expensive for little gain over the 243's especially ported ones. Just something to think about.
Of course this is just in my opinion.

Unless you don't like it's street manners I'd leave it alone and drive it. You aren't going to squeeze much more, if even anything, than what you have out of a naturally aspirated LS6.
If you do want a lot more power then I'd go the supercharger route.

I would replace the gasket(s) and sort out/upgrade anything discovered in the process and enjoy as is.

seeing what your car already makes I think you would be disappointed after spending big bucks on a nice set of heads plus another cam and all the associated parts/installation and make maybe 30hp more than what you are now... for the money you are going to spend on all of that you could buy a blower kit and easily make 200hp over what you have now and even more if you wanted to... just my opinion

STOP! Decide what your goals/uses that you plan for your Corvette, then plan on how to achieve those. At your power level, you're at the cusp of the point of spending alot of money for minor gains, if your needs require a NA setup. As much as I love my BT finished Trickflow heads, I wouldn't have bothered if I would have planned ahead on a supercharger. It's way cheaper to run a little more boost, than to, say, get a ported FAST92 setup, which would be my choice of next mods to stay NA. Unless you scrounge around for used parts, that's about $1500+ for maybe 25 HP. If your budget is more expansive, just SC it next, and replace the head gaskets.
