Both have great reputations, although I have no experience w either. Might want to search over at k20a.org. There is plenty of info on both brands over there.

Stay with stock cams.. best choice
+1
If you want any longevity stay away from anything but stock. K engines timing chain business sucks some serious ass and that chain tensioner appears to operate outside of normal physics with built in aftermarket cam ID feature that self destructs it if you use them.
I am not joking, stretched chains, broken tensioners, skipped timing= K engine with aftermarket cams (or stock cams with 100K or so on the chain/tensioner)

You're talking out of your ass....
A) The tensioners are holding on cars 900+ whp
B) S2 was the major cam manufacturer breaking these tensioners.
C) "that chain tensioner appears to operate outside of normal physics with built in aftermarket cam ID feature that self destructs it if you use them." What the hell does that even mean?
To the OP:
Your not gonna wanna run a tsx head if you wanna make any serious power, your also not going to wanna run stock tsx cams. The best OEM cams for boost are gonna be the k20a2 cams.
Personally I wouldnt run OEM cams, and im not. Drag Cartel 2.2s are perfect for boost regardless of the power goal. They arent to aggressive to make street driving difficult but they will defiantly let you make more power easier. Which means less boost and less stress on the motor.
EDIT: What turbo? what kit? how much boost?

Stock TSX head is out of the question than, and stock cams are starting to as well. Id only be looking at Prayoonto or Cartel.
Are you doing any bottom end work?
I wanted to send a 06 tsx head to 4 pistons to get a head job, do something a bit different then a k20 head. I was also thinking instead of paying $900 for the prayoonto cams maybe I could use the brian crower stage 2 because the specs are pretty similar between the two. Mugen cl9 dyno http://www.k20a.org/forum/showthread.php?t=107269 he's using the brian crower stage 2's
If the meaning of that escapes you, that is fine, you wouldn't probably find it funny.
As far as me talking out of my ass, that is not necessary in this conversation. We are entitled to different opinions I would say.

TSX head is a waste of time, the water jackets are too close. So after porting it, the amount of boost it can handle is much less than a k20a2. Plus it flows much less.
You could use BC 2s but I wouldnt personally recommend them, most guys on k20a are going to recommend either Cartel or Prayoonto.
It kinda sounds like your trying to save some money, If thats the case I would be careful with that power level.
High power, good reliability, or cheap. Pick two, you cant have all 3.

You're giving false info, very false info. Its not an opinion its proven, tried, and true facts.
Daily driven, aftermarket cammed, 700WHP+ TSXs are everywhere and, according to internet, very reliable.
I hope you see my point, there is very few proven facts to be found on these boards and mostly BS posted by people that have interest in doing so.
K engines are notorious for having timing chain issues (even stock), and this is a fact, ask someone working at the dealer.
I understand your point of view, all I am saying there is more to this, there always is.

LOL no but there are many civics in all body styles that are pushing much more than that and are street cars. If you knew what you were talking about you would know that the PRB tensioner is not the one causing the problems, most issues come from older CRVs not ALL K series had this issue. Anyone that is pushing serious power knows the PRB tct is the only one to buy.
Its still a K24, just because its in a TSX doesnt mean all these things that have been proven many times over the past 10 years just get thrown out the window.
A 700+hp K can be just as reliable or even more reliable then a 300 hp K. Money talks.
I think you might want to take a walk over to k20a....
EDIT: The k24a2(TSX) is not one of the motors that had a TCT issue, are there cases of it? Sure things break, but not like they did in the CRVs.
Yes, there are issues with K24a2 all over the place. From burning oil to timing.
Since discussion is on timing, I'll tell you that in my experience (not from k20a forum), but from actually working on this, virtually every k24a2 over 60K has stretched timing chain to some extent. At 100K, all of them do, including automatics.
Eventually, they will throw a code, and if not resolved quickly they will skip timing, you get the idea.
Long story short, OP is going turbo, why introduce another MAJOR point of failure with after market cams? It is virtually guaranteed to go. Build for more boost, and run with a bit more boost if you are wanting for power. Yes, AM cams might get more power under the curve or spool up faster, but not worth it in the long run, especially for daily driver.
If OP was going NA, in that case you have to take good with bad, and cams are such important part of what you are doing that you almost have to go AM to make power, BUT be ready to service EVERY few thousand if you want to keep your motor in one piece.
Anyway, if you are building purpose built race car, I get what you are saying.
I doubt that he would be posting in TSX forum if he was doing that.
On my part, I have seen enough of these summer specials to share something with you of value, I will admit that it is not end result that counts, it is the journey that matters, in which case to each their own.

Did I ever say they had no problems at all? Parts wear thats a fact. Theres a reason why the chain and TCT is supposed to be replaced at a specified interval.
If you truly and honestly think because your running a larger cam that immediately means your chain is going to stretch faster and the TCT is going to wear quicker, I honestly recommend reading up on a few things.
There are hundreds if not thousands of guys that daily boosted Ks with aggressive cams and never have issues. If thats not enough evidence for you than I have no idea what to say to you. Im done trying to get that through to you because there is more than enough evidence to support what Im saying on this site, on k20a, on 8thgen, on rsxclub, on nicoclub, on *insert forum here*.
Anyways OP.....

DONT KNOW IF I SHOULD SHARE MY INPUT SINCE OP WANTS TO MAKE ABOUT SAME POWER AS ME. BUT LIKE tottenham12712 SAID YOU WILL WANT TO STAY AWAY FROM THE TSX HEAD. I WENT WITH THE K20A2 HEAD FULL PORT AND POLISH AND SOME PISTON LOVE. CHECK MY BUILD THREAD 
AS FOR CAMS. IM GOING EITHER WITH KELFORD STAGE 2 OR DRAG CARTEL 2.2

why are you still arguing. You clearly knows what you are talking about. Let him go waste money upgrading his chain. I am running the 2012 si k24 timming chain in my setup.... Just cause i want too . There is nothing wrong with using the stock tsx chain in a high horsepower car

I dont want to see someone build a car on poor advice, Im not doing it for my own personal benefit. There are a lot of people here that want to make there car faster, listening to poor advice and knowledge isnt going to help them.
We have fairly similar setups anyways
Ill be using the PRB TCT and a stock TSX chain.
