LS Build Disappointed
OP, I really do think that there is a lot to gained by installing a really damn good pair of heads. In your case, I would strongly consider aftermarket castings for the better port efficiencies. If head A flows 310 CFM on a 235cc runner and head B flows 310 on a 220cc runner, head B would actually run a bit better with a broader torque curve, giving you more power earlier and carrying a bit farther past peak power. A really well done set of cathedrals on your 414 would really wake the motor up, combined with the right cam (not necessarily the largest, but the right one). On the street I tend to find cathedrals more forgiving of cam specs, and I assume the same is true on the track.
Now, the caveat. Traction. On mine, I couldn't go any faster than I do now, even with a 150-shot of nitrous, because I can't plant the power. I hit 5000 rpm on my way up from 3000, and I'm spinning, unless I'm in 4-6 gear. You're probably already pushing more power than me. Let's say for argument's sake you do a H/C package and are now making 750 FWHP after its done. You might be approaching the point where all that added power makes less of a difference than it should. Without knowing your entire car I can't really say, but you should look into your ability to plant the power to the pavement as well as your ability to make power.

Jesus christ. LOL oh man. Why are you people still going on about heads/cam/power after my posts (especially #56 and #57) 100% PROVED THAT HIS HEADS AND CAM AREN'T THE MAIN PROBLEM?
Is it too much EPICNESS for you to take in and comprehend? Is the light shining around those Holy comments of mine too bright for your eyes? Is American english that different to Rest Of World english and you can't convert it properly or something? Is it because I'm new here and need to write 3,000+ comments of bs first to be taken seriously? Ego's too big to accept that an LS1Tech noob is 100% correct and (some of) you "10 YEAR MEMBER"s are wrong? Is it sheep/herd mentality, you see everyone saying "heads/cam" so then you automatically agree with them and think the 1 guy saying something different is crazy/stupid?

What does that ^ show, kids? HE ALREADY HAS THE POWER (for a 10 second pass) but has a bit of a problem getting off the line and if he improved his 60ft time by 0.1 of a second, then he will be in the 10's! No need for more power! No need for new heads and cam!
Sure, new heads/cam/tune will most likely improve his 1/4 ET and Trap. Then again, so will a 1,200hp engine. What's the difference? Both options cost a lot of money.
Again, the OP has listed a million problems with his car, including transmission problems. New heads and cam should be the least of his worries.
And "big hammer"
you think you're funny?

Thanks for all the advice guys. I know I have several issues that can be tweaked to make the setup I have now quicker. Heads and Cam are planned down the road but at the moment I am working at getting better with suspension and tuning. This is the first LS engine i have ever dealt with, I have built a few sbc in the past but for the LS build I left it all in a very reputable engine builders hands. I asked him to build me a streetable engine that would take a decent shot of nitrous and apparently he took the streetable part too far.

you think you're funny?Oh yeah what's the weight of those cars compared to the OP's? what rpm do they shift at? DA?

There is nothing wrong with being streetable. Hell, the completely streetable 2016 Camaro is ripping down the quarter in 12 flat off the showroom floor. Just like anything else, there are trade-offs. Cars built for the street don't perform as well on the drag strip as a car built for the drag strip, just as a car built for the drag strip doesn't perform as well on a road course as a car built for the road course. It boils down to what you want.
However, I really do think that you need to optimize the tune, work on the suspension, and get more seat time in the car. There is time left on the table without question, but I think you can find some of that time before tearing back into the engine.

if your running a 414 ci you need something in the 239/250 duration and 650 lift to really wake it up. and 122 is with a sixty of 1.6. its not gaining like it should. you need to throw some cnc ls3 heads and intake on it with a bigger cam. get that air fuel right. you can also run some .40 gaskets and get your compression up. I trap about 128 to 129 with my 6 spd 418 for comparrison with 1.5 sixty
just giving you options on how to optimize all those cubic inches. you can make the heads and cam you have work just get that air fuel in the 13s. also if your auto with a base line tune the transmission itself might need some tuning to help with your et and trap

This Chevy guy, so much anger...smh 
So according to his math if I shave off .1 on my 60 ft I can be in the 11.0 range with full weight...well sign me up
OP, By the looks of the info you posted of the 11.6 run it almost seems like it's falling on it face mid track and then picking back up to get you decent mph. I asked in your other thread and still would like to know what your 1/8 mph was. 7.3 in the 1/8 should be netting you in the 11.3-11.2 range.

After destroying everyone here (who doubted me and laughed at me...) in the a$$ and making them my b*tch, I still get an ignorant clown laughing at my posts (which are clearly 100% correct) a month later.
I dont see a dyno anywhere. If we had a dynojet graph we could compare displacement to torque/"VE" and get some idea of how well the engine is using its displacement, and how much the drivetrain is eating.
I think the next step is a pass on a dynojet.

Not sure what your problem is....the heads are most likely choking the engine at higher rpms and the cam isn't amazing.....
I don't wanna argue. But .1 doesn't always equal what you think it does....we don't know how his car pulls in higher rpms and if there really is a tranny issue....
His afr is off....I mean that's an issue that needs to be worked on....it could be causing issues....just saying. Don't destroy me.
OP do you have dyno numbers and a graph? That would definitely show us your curve and help with engine sugestions.
