Building heads. What components?
First off, let me say that I have tried to dig up chatter on this subject with little to no resulting info, so hopefully anything discussed here will be helpful to anyone else looking for the same in the future.
I've never had an interest in piecing together heads before, so I am at a bit of a loss.
I currently have a C6 Grand Sport LS3 6spd Coupe w/Dry Sump that I plan on tasking with light to moderate track duty in the near future, but am looking to try to make the valve train as bulletproof as possible. My goals may be slightly lofty, but I would like 505hp naturally aspirated at the rear wheels (gotta keep up with those Z06s, right?) with a stock bottom end. I/TB/IM/H/XP/E should be a good start, and I would like to add a set of the Trick Flow 255 heads into the mix to help with the inhaling and to match the exhaling of the motor. A cam and tune will hopefully be installed at the same time as the heads to complete the package.
Now, I have been trying to piece together what components would work best on an NA application, but all I have come up with is "lighter is better!" everywhere I look. From what I gather, Ti valves would be helpful, the rockers (and trunions?) would need to be upgraded as well as springs (dual springs? what lb. strength?), retainers, and push-rods. Any help, direction, or insight would be greatly appreciated here.
If my goals are too lofty, please, let me know.

Another great person to ask is the guy you plan on getting to tune your car. He should have an idea of what works and what he thinks is possible. no one see's dyno numbers quite as much as a tuner so that's the guy you talk to first, then get him to help you find a package that he knows works and knows the potential outcome.
Nothing is more crucial to choosing the "right" things that work together. Your tuner should be able to help you choose the right combo.

255's are a massive overkill for a stock shortblock IMO, and not really necessary. You can make 500rwhp (or very close to it) with the stock square port castings as long as their done correctly and the cam choice is on point.
When you say track duty are you referring to drag strip or road course racing?

If you want trickflow heads, why not ask them what they recommend for your goal/needs. There is a point where you start spending money to get the absolute best on paper but won't give you much return in comparison from a cost/performance aspect. Plus they'd sell you the heads fully assembled ready to go. Light is key if you plan on really revving that engine, but you'd need a better rotating assembly to pull off crazy revs so some of the components may be overkill.

BTR is another good resource to call. Thanks!

"Track Duty" for me means road courses. All due respect to drag racers, but it is just not for me.
